[PATCH resend 2/2] Don't try and percent-escape existing percent escapes in git-svn URIs

[Kevin Ballard <kevin@sb.org>]

git-svn: project names are percent-escaped ever since f5530b.
Unfortunately this breaks the scenario where the user hands git-svn
an already-escaped URI. Fix the regexp to skip over what looks like
existing percent escapes, and test this scenario.
