[PATCH 1/1] git-submodule.sh: fix relative paths with ssh urls

[Russell Yanofsky]

Fix handling of submodule urls starting with ../ when the remote url is
an scp-style URL with the format user@host.xz:repo.git. For example, if
the remote url is user@host.xz:repo.git and the submodule URL is
../submodule.git, the combined default URL will now be
user@host.xz:submodule.git instead of
user@host.xz:repo.git/submodule.git.
