2b4cf04281 fix gamelog 1st kill vs 1st weapon hit sequencing
If the first monster the hero kills is killed by the hero's first hit
with a wielded weapon, report the hit first and kill second instead of
the other way around.  Not as hard to manage as I feared, but bound to
be more fragile than the simpler handling that produced the odd order.

Also while testing it I knocked something into a polymorph trap and it
changed form without any feedback.  Give foo-changes-into-bar message
if the hero is moving and can see it happening.  It isn't needed with
a monster moves deliberately into a polymorph trap but probably would
be useful when that's is unintentional.

The "<hero> enters the dungeon" log message had a trailing period but
other log messages don't have sentence punctuation, so take that off.

cd797afd0e Don't show rusting of items landing in water
When a thrown item lands in a pool of water, it immediately
rusts - but don't give that message unless the hero is at the same
location and also under the water.  My reasoning: hero can't see items
under water, and by the time the item rusts, it's in the water.

f233f1d18c water description
The wall of water goaded me into updating waterbody_name().  It's
mostly the same, aside from being moved from mkmaze.c to pager.c and
adding "{wall of|limitless} water" instead of plain "water" for WATER
terrain.  I'm not very happy with "limitless" for the Plane of Water
because limits imposed by air bubbles are all over the place.  "Wall
of water" might work ok for that level.

Water on Medusa's level is now described as "shallow sea" rather than
lame "water".  The two unusual pools on the Samurai home level are
described as "pond" rather than previous "water" which replaced 3.6's
ridiculous "moat".  When lava is hallucinated, it is described as
"molten <substance>" (yielding silly things like "molten yoghurt"),
rather than just "<substance>" to distinguish it from hallucinated
water.  'autodescribe' doesn't use waterbody_name() though.

4ee1c66f8f Make solid water behave more consistently
The "water" terrain (as used on the Plane of Water) behaved
strangely outside the plane. Make it behave a bit more consistently,
although it's still not really usable elsewhere.

The rationale here being it's a solid wall of water.

Firstly, disable levitation and flying (which was already done
when moving into the water on the Plane of Water), and moving into
it refers to it as a "wall of water" to make it clear it's a solid
block of water.

9aea7b587c fix #K3455 - rocks vs xorns
Implement the suggestion that falling rock traps and rolling boulder
traps be harmless to xorns.  I've extended that to all missiles made
of stone (rocks, gems, boulders, a handful of other things that will
only matter if poly'd hero throws in '<' direction or is hit by stuff
scattered by an explosion).

I excluded ghosts because they would become even harder to kill and
the missile handling would need extra checks to test for blessed objs.

0aafe11515 Don't erase Elbereth when monster steps into a pit or hole dug by you
Elbereth was fading when offscreen monsters stepped into
pits or holes dug elsewhere on the level. This was happening
because monsters falling into traps set by you were calling
setmangry() as if you had just attacked them. The behavior
made it unsafe to use Elbereth if you've dug down anywhere
else on the level, making it a bit harder to get archeologists
off the ground.

d53cd28d46 Make extended commands return defined flags
Instead of returning 0 or 1, we'll now use ECMD_OK or ECMD_TURN.
These have the same meaning as the hardcoded numbers; ECMD_TURN
means the command uses a turn.

In future, could add eg. a flag denoting "user cancelled command"
or "command failed", and should clear eg. the cmdq.

Mostly this was simply replacing return values with the defines
in the extended commands, so hopefully I didn't break anything.

495cda17b7 some reformatting
Replace some
  (foo &&
   bar)
that had crept back into the code with
  (foo

to match the reformatting which took place before 3.6.0.  There are a
couple of lines ending in '||' still present but they look intentional.
isaac64.c has some trailing '|' bit operators that could/should be
moved to the start of the next line but I didn't touch that file.

While in the affected files, I tried to shorten most overly wide lines
(the right margin is supposed to at column 78 and there are quite a
few lines which are 79 characters long, but I left most of those
rather than introduce new line splits).  Also replace a handful of
tabs with spaces.  I was a little surprised not find any trailing
spaces (in the dozen or so files being updated).  I didn't look for
trailing arithmetic or '?'/':' operators which aught to be moved to
the start of the next line.

d26537c4c9 fix github issue #608 - #untrap vs web
Reported by Vivit-R, the chance of freeing a monster from being
trapped in a web was very small and failure resulted in creation of
a new web at the hero's spot, eventually making it impossible to
attempt to #untrap the monster (if hero escaped the new web and moved
to another spot adjacent to trapped monster, eventually surrounding
it with webs).  [That's actually misleading.  Escaping the new web
but staying at the same spot lets the player try again; repeat as
needed....  But chance of failure still seemed way too high.]

This reduces the chance of failure from 29/30 to 6/7 and makes the
chance of spreading the web after failure be 1/3 instead of 100%.  It
also supplies missing feedback about the monster still being trapped
if the attempt to make a new web fails.

b4908f6928 fix pull request #621 - potential divide by 0
The pull request by argrath changes weight_cap() to never return a
value less than 1 because try_lift() divides by that return value
and a 0 would trigger a crash.  The code involved is used when
attempting to pull a monster out of a pit via #untrap.

I'm fairly sure that weight_cap() can never produce a value that's
less than 1 already, but have put in a variation of the PR's fix.
I've also implemented a different fix that removes the division
from try_lift().  The original code seems to have gone out of its
way to avoid calculating inv_weight() twice, but doing the latter
(for the once in a hundred games where it might happen) greatly
simplifies things by removing details of carrying capacity.

e5f96cd329 diagonal movement glitch
|..X..
|.X}X.
|..X..
When testing the odd Samuari moats, I discovered that you could
easily walk diagonally between any two of the solid stone pillars
and fall into the water but you would always drown because it's a
no-teleport level and the crawl routine wouldn't let you back out
via that same diagonal.

The crawl routine is also being used by travel for the last step--a
post 3.6 change--so there was an unnecessary restriction on diagonal
movement there too.

Revive some code from 5 or so years ago that's been sitting in a

mon_pmname(mon) and some
pmname(&mons[statue->corpsenm],

Dead monsters that had traits saved with the corpse would revive as

f90bb4fb6b container vulnerability to water damage
We used to have the contents of chests and large boxes be immune to
water damage, oilskin sacks immune unless the sack was cursed, other
containers be vulnerable.  Some reddit discussion about ice boxes in
unnethack indicates that they are treated like oilskin sacks, which
makes sense.  This adds that to nethack and also makes chests and
large boxes behave similarly.  So it's now:  nothing is immune even
when cursed (except statues); oilskin sacks, ice boxes, and other
boxes are immune to water damage unless cursed; all other containers
vulnerable even when not cursed.

I suspect that the old ice box classification might have been an
accident caused by the Is_box() predicate yielding False for it.

The changes won't make much difference to actual play.  Chests and
large boxes are rarely carried and never start out cursed, ice boxes
even more so, and sacks/bags haven't been changed.  However, players
might intentionally curse a container to keep strong pets from
picking it up, or be carrying a box because they haven't found a bag
yet and then muck about with fountains or thrones and get it cursed.

8bd08ebb71 level teleporters vs Ft.Ludios
From newsgroup discussion where slash'em changes have revealed a
latent nethack bug:  prevent placing level teleporters in single-
level branches.  The Knox level doesn't have any level teleporters
(or random traps) but wizard mode wishing could create them there.
They wouldn't do anything because the only possible destination
would be the same level.  Pushing a boulder onto one used to trigger
an infinite loop (and still does in slash'em, which has other
single-level branches besides Ft.Ludios) trying to relocate it.

Boulder pushing was changed 15 years ago to prevent the infinite
loop and to avoid giving "the boulder disappears" message when a
level teleporter failed, but rolling boulder traversal lacked that
same change--it wasn't vulnerable to looping but could give an
inaccurate message claiming that the boulder disappeared when it
actually didn't.  Fixing this is a bit late; rolling boulder trap
creation was recently changed to not choose a path that rolls over
teleportation or level tele traps any more.

0b638592a4 Refactor getobj() to use callbacks on candidate objects
This replaces the arcane system previously used by getobj where the
caller would pass in a "string" whose characters were object class
numbers, with the first up to four characters being special constants
that effectively acted as flags and had to be in a certain order.
Because there are many places where getobj must behave more granularly
than just object class filtering, this was supplemented by over a
hundred lines enumerating all these special cases and "ugly checks", as
well as other ugly code spread around in getobj callers that formatted
the "string".

Now, getobj callers pass in a callback which will return one of five
possible values for any given object in the player's inventory. The
logic of determining the eligibility of a given object is handled in the
caller, which greatly simplifies the code and makes it clearer to read.
Particularly since there's no real need to cram everything into one if
statement.

This is related to pull request #77 by FIQ; it's largely a
reimplementation of its callbacks system, without doing a bigger than
necessary refactor of getobj or adding the ability to select a
floor/trap/dungeon feature with getobj. Differences in implementation
are mostly minor:
- using enum constants for returns instead of magic numbers
- 5 possible return values for callbacks instead of 3, due to trying to
  make it behave exactly as it did previously. PR #77 would sometimes
  outright exclude objects because it lacked semantics for invalid
  objects that should be selectable anyway, or give slightly different
  messages.
- passing a bitmask of flags to getobj rather than booleans (easier to
  add more flags later - such as FIQ's "allow floor features" flag, if
  that becomes desirable)
- renaming some of getobj's variables to clearer versions
- naming all callbacks consistently with "_ok"
- generally more comments explaining things

The callbacks use the same logic from getobj_obj_exclude,
getobj_obj_exclude_too and getobj_obj_acceptable_unlisted (and in a few
cases, from special cases still within getobj). In a number of them, I
added comments suggesting possible further refinements to what is and
isn't eligible (e.g. should a bullwhip really be presented as a
candidate for readying a thrown weapon?)

This also removed ALLOW_COUNT and ALLOW_NONE, relics of the old system,
and moved ALLOW_ALL's definition into detect.c which is the only place
it's used now (unrelated to getobj). The ALLOW_ALL functionality still
exists as the GETOBJ_PROMPT flag, because its main use is to force
getobj to prompt for input even if nothing is valid.

I did not refactor ggetobj() as part of this change.

2df4f08c0b Add liquid flow to land mine explosions
Land mine explosions did not call liquid_flow(dig.c), and as a result
the pit created by an exploding land mine would never fill with adjacent
water or lava, as pits created by other sources -- digging, breaking a
wand, and earthquake -- can do.

This commit adds the appropriate calls to liquid_flow and fillholetyp to
blow_up_landmine so that land mine explosions may fill with water like
other pits do.

The call to losehp in dotrap had to be moved from after to before
blow_up_landmine, since waiting to call losehp when the pit can fill
with water could lead to silly messages (``That was a close one. You
die...''). After this change, a land mine that killed a character would
be retained unexploded in a bones file, because death would occur before
the call to blow_up_landmine. To avoid this issue, the land mine is
converted to a pit before calling losehp; blow_up_landmine does not
check whether the target trap is in fact a landmine so works as usual
even if the trap is converted to a pit, and will delete the pit in cases
where it should not exist.
