From: "Michael G. Schwern" <schw...@pobox.com>
Previously, our URL canonicalization didn't do much of anything.
Now it actually escapes and collapses slashes. This is mostly a cut & paste
of escape_url from git-svn.
This is closer to how SVN 1.7's canonicalization behaves. Doing it with
1.6 lets us chase down some problems caused by more effective canonicalization
without having to deal with all the other 1.7 issues on top of that.
* Remote URLs have to be canonicalized otherwise Git::SVN->find_existing_remote
will think they're different.
* The SVN remote is now written to the git config canonicalized. That
should be ok. Adjust a test to account for that.
