Yes.  Please maintain compatibility with svn 1.5.  The current version
of git-svn should strive to maintain compatibility with the current
version of svn whenever possible.

It should match svn 1.5 for "git svn info".

Since "git svn info --url" is a git-svn-only thing, whatever makes the
most sense from a command-line scripting perspective (I don't have time
to check against a real repo right now):

For git-svn info --url, just want things like:

	svn log -v `git svn info --url`

	svn cp `git svn info --url` \
               `git svn info --url | sed -e 's,/trunk,/tags/1.0,'`

	svn rm `git svn info --url`

to just work.

I seem to recall the rules being slightly different for http(s):// and
(file://|svn://) URLs with the command-line client; but my memory may
just be fuzzy...

Thanks for looking into this!
