[PATCH/RFC] git-svn: sanitize_remote_name should accept underscores.

[Avery Pennarun <apenwarr@gmail.com>]

Without this patch, git-svn failed with the error:
 config --get svn-remote.D2007.Win32.url: command returned error: 1

...upon trying to automatically follow a link from a child branch back to
its parent branch D2007_Win32 (note the underscore, not dot, separating the
two words).

Note that I have each of my branches defined (by hand) as separate
svn-remote entries in .git/config since my svn repository layout is
nonstandard.

I'm not sure why sanitize_remote_name is so picky about allowed characters,
but underscore should certainly be allowed.  I'm worried that this has
revealed a more serious problem, since presumably sanitizing the name
shouldn't break anything in any case.
