Add a man page for makedefs so mdgrep is documented better.
Add missing INSURANCE to mdgrep.h. (yes, LIFE leaks in as well)
Add makefile bits to build makedefs.txt.
Pass dungeon.def through mdgrep internally to makedefs - this will make
it possible to commit the LIFE patch and have config.h actually turn it
all the way off (by skipping bigrm-6).
If SHELLDIR is null, don't install nethack.sh. Also a tid in Porting
and add NHSROOT to the Makefiles which gives a path to the top of the
tree (so e.g. you can always find makedefs from a rule in a hints file).
use makedefs --grep in Makefile.doc
call make clean in doc from make clean in top
add commented out rule to produce mdgrep.h from mdgrep.pl
macosx1.5: don't chown/chgrp for single-user install
unixmain.c: work around C90 warning for Mac-specific code, fix last fix
makedefs.c: temporarily disallow blank after control introducer until docs
catch up
mdgrep.pl: add ALLDOCS, clean up generated file's header
Last fall when Michael added the symset stuff to supersede the old
handling for IBMgraphics and DECgraphics, Guidebook.tex was changed to
support multi-page tables in the output. But that requires that the
input be processed twice, because it requires feedback stored in
Guidebook.aux and the first pass can't rely on that file being present
or up to date. This updates the Unix, VMS, and OS/2 makefiles to do
two-pass processing. (I didn't see latex usage anywhere else, and the
branch version doesn't include the formatting change which needs this.)
I found that the setting of GUIDECMD sys/unix/Makefile.doc didn't cut
it with groff-1.18. Also, the command was duplicated in the rule to
generate Guidebook.txt.
