[PATCH] "git svn clone" fails when tags have illegal url characters in them.

["Jerry Seutter" <jseutter@gmail.com>]

Found a repository with a tag that had a hash (#) mark in the tag name.
The svn repository was available via WebDAV. "git svn clone <url>" would
generate an invalid url when trying to fetch the tag, causing a server
400 result on the other end of the connection.

The fix is to escape the url correctly.  This is a quick and dirty
hack that copies two functions from earlier in the file - only the last
line modified in the commit is important.
