```
Cloning/initializing svn repositories with an uncanonicalize url does not
work as libsvn throws an assertion. This patch canonicalize svn uris for the
clone and init command from git-svn.

Thanks,

I'm not getting any assertions in my version of SVN (1.5.1) but it
actually does cause issues with path stripping when following
repositories.

Acked-by: Eric Wong <normalperson@yhbt.net>
..and pushed out to git://git.bogomips.org/git-svn

There was a minor trailing whitespace issue which I fixed, too
