Move some 'roff macros from Guidebook.mn to new file tmac.nh.
Header for tmac.nh is not being updated, even after explicitly adding
it to .gitattributes. I'm not sure what I've done wrong. (I'm using
'git nhadd doc/' here rather than explicit 'git nhadd doc/tmac.nh'.)
In Guidebook.mn, change the ``setenv NETHACKOPTIONS'' example so that
it fits within one line in Guidebook.txt. (I looked at 3.4.3's
edition of that file and the example went not just beyond the margin
of the formatted text but beyond 80 columns, so wrapped in an ugly
fashion.) I had previously changed 'autoquiver' to 'color' to shorten
it, now have changed '!autopickup' to '!leg' to show an example of
truncated option name as well as shorten, and also 'fruit:papaya' to
'fruit:lime' to squeeze out the last two columns needed to fit within
the text margin while retaining 'name:Blue Meanie' as requested.
Guidebook.txt shows both NETHACKOPTIONS examples with indentation
suppressed, Guidebook.ps uses normal indentation (evidently using a
narrower font, even with \f(CR (constant-width Roman) to approximate
TeX's \tt, since the indented example fits fine and looks better).
Some Guidebook.tex catchup. I suspect that lots of bits and bobs
don't match between Guidebook.mn and Guidebook.tex these days.
Particularly quoting and variant font (italics, bold, \tt) usage.
Also the recently added box around the sample screenshot. This
modifies the screenshot to match Guidebook.mn's, reflecting change
in status field spacing by STATUS_HILITES.
Change the extended command section from a mixture of
|#cmd This is a short-named command.
|#command
| This is a long-named command.
to every command having its descriptive text start on the next line
|#cmd
| This is a short-named command.
|#command
| This is a long-named command.
which results in a longer document but the extended commands section
is much easier to read.
No change to Guidebook.txt, where the previous command name padding
was wide enough to accomplish the same for fixed-width tty font.
There is an update to that though; a previous change omitted it.
I may not get around to doing anything with 'C' vs `C' vs \(oqC\(cq
for a while. Bring Guidebook.txt up to date now rather than waiting
so that the repository's copy reflects the #H7444 fix.
This has ended up with substantial spurious differences due to it
placing padding in different spots during line justification. I
hope that's due to different groff version using a slightly different
algorithm rather than something like phase of the moon. :-]
There also differences caused by "..." taking less space than ``...''.
