recover had deviated somewhat from NetHack in its
file expectations:
1) A couple of 3.7 fields needed to be accommodated.
2) hard-coded file size values had deviated.
The file sizes are now in an added header file named "filesize.h",
which is included at the bottom of config.h.
There will likely be another commit to write the filename size ahead
of the file name so that the precise number of characters can be read,
but since that will break existing saves, it can go in along with another
save-breaking commit.
This commit doesn't not alter savefiles written by nethack so does not
require an editlevel bump. It does alter the read-in expectation in
recover to match the game and this get recover working again.
Moved the code page 437 mapping table to winnt.c so that it could be
used in window and console clients.
Added check that fonts support unicode values we use from code page 437.
Use unicode to draw text if font supports it otherwise use ASCII.
Change lev_comp's add_opvars() to be like pline(), where there's a
single visible opening brace and a second one hidden in VA_DECL2
that introduces a nested block, plus a single visible closing brace
with a hidden one in VA_END() to close the nested block. This
addresses the erroneous report (sent directly to devteam, so no #H
number, subject "missing '{' in util/lev_main.c:634") that the code
for !USE_STDARG/!USE_VARARGS in add_opvars() wouldn't compile.
Also, fix the part of "#H5778: file descriptor leaks" dealing with
util/recover.c -- an open file not being closed after various errors.
I didn't take responsibility for this entry in the bugzilla list
since the report includes similar problems in other code that's not
addressed here.
And a blast from the past: some reformatting fixups in recover.c.
The most interesting bit is for a block of dead code....
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!

It turns out that the processentry32 structure contents
are slightly different on 2000/XP than they are on
95/98/Me according to the docs.
szExeFile
Pointer to a null-terminated string that specifies the name
of the executable file for the process.
Windows 2000/XP: The file name does not include the path.
Windows 95/98/Me: The file name includes the path.
Ensure that we check for the target values at the end of
the string.
