meld shows modified files with cvsnt, but won't compare

[Steve Franks <stevefranks ieee org>]

Happy to find a diff that's interested in talking to source control,
since most cvs's seem to think everyone should be able to parse diff
output manually (not one of my strong suits)!

Anyone attempt to use Meld 1.1.5.1 with cvsnt?  I don't see why it
shouldn't work, but I've never found a tool that works with cvsnt,
even though all options are compatible with regular cvs at the manpage
level ("cvsnt -z9 -q update -r xyz file" works).  My protocol
(sserver) is different (from pserver or ssh) but that's hidden by cvs
if you use the executable instead of parsing the CVS folder...

When I open a folder with files under cvsnt in it, it correctly shows
all modified files, but "compare" won't show differences from the
repository (maybe that's not what it's supposed to do?)  This seems to
indicate that meld is talking to cvs which is talking to the
repository correctly.  Don't tell me I have to write a script to check
out a temp copy from the repository and stuff it into meld?

Also, if I browse to the cvsnt executable in settings/preferences/cvs,
the next time I open the preferences, it's back to /usr/bin/cvs
(instead of /usr/local/bin/cvsnt) - perhaps this is part of the
problem?

While we're at it, is SVN support planned?

Thanks,
Steve
