[9fans] hg on plan 9

looks like spaces in file names are a problem, at least
on my system.

i know that. it's just more difficult than necessary to put stuff like
that in the repo.

there used to be a hack in Hg to safely store files with spaces (and other
potentially unsafe characters) in names, called `fncache repository format'.

http://mercurial.selenic.com/wiki/fncacheRepoFormat

seems you can toggle it on/off in config.

For example, if the first thing in the file is:
<?kzy irefvba="1.0" rapbqvat="ebg13"?>
an XML parser will recognize that the document is stored in the traditional
ROT13 encoding.

I made a change to hg:

mercurial/store.py:
in def _buildencodefun():
- win_reserved = [ord(x) for x in '\\:*?"<>|']
+ win_reserved = [ord(x) for x in '\\:*?"<>| ']

in def _build_lower_encodefun():
- win_reserved = [ord(x) for x in '\\:*?"<>|']
+ win_reserved = [ord(x) for x in '\\:*?"<>| ']

This got me through the errors with filenames
with spaces in them (it converts spaces to '~')
but I have errors of a different sort now:

Anyone have a more thorough patch?


Thanks,
