7b1ec30d0d bounds checking by doname() and xname()
Try harder to prevent buffer overflow when formatting objects.
I don't have any test cases where overflow has been happening so
don't really know whether this works reliably.  And it doesn't try
to check prefix construction by doname().  [Yet?]

6b8079a16f secondary damage for monster spell attacks
Have monster spells
| "shower of missiles" (AT_MAGC+AD_MAGM: Angels, Yeenoghu)
scuff an engraving at the hero's spot if there is one,
| "frost" (AT_MAGC+AD_COLD: only Asmodeus)
freeze water and lava terrain,
| "flames" (AT_MAGC+AD_FIRE: moot, no monster has this attack)
burn items on the floor at the hero's spot and melt ice terrain,
| "pillar of flame" (AT_MAGC+AD_CLRC+randomly chosen clerical spell)
which already burns floor items, melt ice too, and
| "lightning" (same casters as pillar of flame)
give a tiny chance of destroying iron bars.  The chance to hit bars
is low and the hero has to be targeted while located on an iron bars
spot so probably won't happen before the sun burns out, but only
needed one extra line of code.

Only the first two have been thoroughly tested.

3160112ece Accessibility: Show a message when monster is spotted
Adds a new boolean option, spot_monsters.  If on, every time
the hero notices a monster which was out of sight before,
a message is given.  Combine with accessiblemsg to get the
monster location:

(3north): You see a newt.

627b40fb57 redo monsters.h
Change MON(name, ...) to MON(NAM(name), ...) and get rid of MON3(),
replacing it with MON(NAMS(malename,femalename,neutername), ...).
That eliminates the macro which uses 16 parameters.  Standard C
allows compilers to impose a limit of 15, rejecting 16 or more while
still being in compliance.

That necessitated some reformatting since it made the first line of
each entry longer.  Shorten that by having all entries start with
name(s) and symbol on the first line, then LVL() and generation flags
on the second line, then attacks start on the third.

Reformat attacks to change ATTK(one) + 4 * NO_ATTK on one line plus
an orphaned NO_ATTK on the next line to always use ATTK(one) on first
line and all 5 NO_ATTKs on the next line.  Similarly, change ATTK(1of2)
ATTK(2of2) NO_ATTK on one line followed by 3 * NO_ATTK on the next line
into ATTK(1of2) ATTK(2of2) followed by 4 NO_ATTKS.  For three attacks,
list two on the first line then the third and 3 * NO_ATTK on the next.
Four or more attacks use a third line; ATTK(1of4+) ATTK(2of4+) on the
first, ATTK(3of4+) ATTK(4of4+) on the second, and whatever's left on
the third.  SIZ() follows on its own line for each of the cases.

Split the final line of each entry so that the difficulty value is the
first thing on that line, followed by color and enum tag.  This may or
may not make moving the difficulty into LVL() easier someday (which
would have been an alternate way to reduce the 16 args that MON3 had).

The file gets stretched out by many lines but entries should be easier
to read (matter of taste, I suppose).

I didn't attempt to clean up M1_foo, M2_bar, M3_quux; too hard....
I also didn't touch SIZ() or resistances which are less cluttered than
the other stuff.

0c9e34832c Make HoOA confuse the hero, summon erinyes
A helmet psychically reaching inside your head and twiddling knobs in
your brain must be a confusing experience.  And the instant rejection of
your god (not to mention the vow that you made to find the amulet for
them), perhaps on the very cusp of their ascendance over the other gods,
is sort of the ultimate oathbreaking, so it interests the erinyes.

f930a12fba Make erinyes scale with alignment abuse
Consistent with their mythological role of punishing those who had
violated societal taboos -- oathbreakers, hosts who attacked their
guests, etc -- erinyes scale with the cumulative amount of alignment
abuse the hero has committed over the course of the game.  This is
tracked separately from the alignment record, and cannot be cleared by
the hero improving her favor with her god via "good deeds" as the normal
alignment record can.  Erinyes will gain abilities, levels, and attacks
as the hero's alignment abuse worsens.  They will also aggravate
monsters when near the hero.

c6897bf331 fix github issue #1191 - obj->age of oil potions
Issue reported by AmyBSOD:  several actions change the object type of
a potion rather than force creation of a replacement one, and if/when
the type was changed to oil, the age wasn't converted from absolute
to relative.  Relative age is the amount available and/or the number
of turns it will burn if applied.  The later in a game a potion got
converted into oil, the longer it would burn.  Not mentioned:  reverse
situation was also the case, although that didn't have any noticeable
effect since incorrect absolute age of former oil doesn't matter.

Not thoroughly tested.  I got a potion of oil from a horn of plenty
and it burned for 400 turns, but it might have been created directly
rather than be a rejected magic potion that was converted into oil.

1cfa966871 pull request #1143 - menustyle:Full 'A' choice
Pull request from entrez:  in the class filtering menu for multi-drop
and for loot in-or-out of a container, make choosing 'A' without any
other filter choices (such as all, specific class(es), cursed, unpaid,
just-picked-up, &c) become a no-op.

I started with the pull request and then undid much of it.  It would
have been simpler to start from scratch.  If you don't have option
paranoid_confirmation:AutoAll set, when choosing 'A' for all-without-
prompting as the only selection, operate as the PR has made things
work:  effectively, 'A' by itself is ignored and the operation ends
with nothing happening.

However, if you do have paranoid_confirm:A set, then continue treating
'A' by itself as if 'A'+'a':  everything.  Since paranoid confirmation
is specified, that will be followed by a confirmation prompt.

This also adds a context-sensitive hint to the menu about how the 'A'
entry works, shown every time when 'cmdassist' is On or just once (per
session) when that is Off.

The documentation probably needs some updating.

cb5e93e9e5 polymorphing into placeholder monsters
"human", "dwarf", "elf", "gnome", and "orc" are all flagged M2_NOPOLY;
so is "giant".  But dwarf and gnome are ordinary monsters and should
be eligible to be polymorph targets, so take the no-poly flag off of
them.  The others are used for corpses and not intended to be distinct
monsters.  But they are reasonable polymorph targets, so if player
with control picks any of them, choose a substitute.  The exception is
human, which already has special poly-self handling.

05cf948007 fix github issue #1186 - eating Medusa's corpse
and having temporary stoning resistance timeout before finishing.

Issue reported by Umbire:  hero was able to finish eating Medusa's
corpse safely after getting the message about no longer being
protected against stoning that is given when temporary resistance
times out.

The eating code was extending temporary resistance--when eating
something protected by such--to avoid just that.  I thought this
was probably a message sequencing situation but it turns out that
the code was using touch_petrifies() to test the meal.  It should
use flesh_petrifies() instead; Medusa doesn't pass touch_petrifies().

I didn't figure that out until after rewriting how the duration is
extended.  The old way probably would have worked as desired with
the revised petrify test but I'm checking in the new version anyway.

7a533a911c enhance timer sanity checks a bit
Four kinds of timers are defined but only two have ever been used.
Have sanity checking complain if the other two occur or if 'kind'
doesn't match any of the four.

Also, replacing a perfectly normal use of isok() with an inline test
just to pacify static analysis feels like a slippery slope, so handle
that a little differently.

I reordered the shrink_glob timer to put all object timers together.
Unfortunately that warrants incrementing EDITLEVEL which invalidates
existing save files.

5e9358b331 makedefs: check input files for non-ASCII chars
If MAKEDEFS_FILTER_NONASCII is defined (which config.h now does by
default), it will check data.base, rumors.*, and {various}.txt for
characters outside the range of ' ' through '~'.  If it finds any, it
will warn about them and change them to '#'.

Tab handling is incomplete; the files that use tabs for indentation
will allow tabs anywhere, even though that's not wanted.  That could
be fixed but doesn't seem particularly urgent.  This is more about
spotting and repairing the special 3-char punctuation characters that
crept into data.base fairly recently.
