Rebuild doc/*.txt (other than Guidebook) with 'nroff -man -c -Tascii'
rather than just 'nroff -man' to prevent it generating non-ASCII
characters for hyphen, aprostrophe, single and double quotes, long
dash, possibly others. Also preprocess with '--grep-define ALLDOCS'
so that a few parts of the text don't end up being specific to the
local configuration.
The next time they're rebuilt they'll probably be subject to the
ping-pong effect of inserting padding spaces for justification
(alternating right-to-left vs left-to-right as intended but starting
with different parity so lots of gratuitous changes) since my quite
old version of groff triggers that for Guidebook.txt.
When I updated recover.6 last week, I was under the mis-impression that
the INSURANCE compile-time option had been made unconditional. It has
not, and after undoing that, there was no substantive change, so put it
back to how it was at release.
Update the man pages and generated text copies for nethack and recover.
I haven't looked at the other four (dlb, makedefs, dgn_comp, lev_comp).
recover's page referred to INSURANCE as being conditional, which is no
longer the case. nethack's page was missing a bunch of files to be
found in the playground and also a couple of environment variables.
I haven't read through the text of the page to try to see whether other
updates are warranted.
The generated text is wider than the previous copy (one or two space
right margin instead of 5 or so). I just used 'make nethack.txt' and
'make recover.txt' so don't know why that changed. (The older, wider
margin looks better, so if anyone knows how to fix this, please do.
And there's got to be a better way to force a blank line inside a
table than my <space><tab> hack.)
