Subject: [PATCH] submodule: Improve handling of relative submodule URLs.
Message-ID: <1267126109-14638-1-git-send-email-jacob.helwig@gmail.com>

```
Relative URLs only worked with <proto>://<host>/<location> style URLs, and
would break when cloning a repository using <user>@<host>:<location> (scp)
style "URL"s.

When a submodule's URL was set to "../submodule.git", and the repository
using it was cloned from "git@example.com:repo.git", git would try to
clone the submodule from "git@example.com:repo.git/submodule.git", which
would not likely work.

This updates resolve_relative_url to handle the scp style URLs.

My solution for this has been to always give the full path, possibly using ~

e.g.,     git@example.com:~/repo.git

and as that works fine, I'm indifferent to this proposed change.
