Here's a pair of patches that address some of the bugs I was alluding
to.  Patch 1 makes _canonicalize_url_ourselves() match Subversion's
own canonicalization behavior more closely, though even with that
patch it still does not meet Subversion's requirements perfectly
(e.g., "%ab" is not canonicalized to "%AB").  Patch 2 makes that not
matter by using svn_path_canonicalize() when possible, which is the
standard way to do this kind of thing.

Sorry for the lack of clarity before.

Jonathan Nieder (2):
  git svn: do not overescape URLs (fallback case)
  Git::SVN::Utils::canonicalize_url: use svn_path_canonicalize when
    available
