[PATCH] git-submodule.sh - Remove trailing / from URL if found

[Mark Levedahl <mlevedahl@gmail.com>]

git clone does not complain if a trailing '/' is included in the origin
URL, but doing so causes resolution of a submodule's URL relative to the
superproject to fail. Trailing /'s are likely when cloning locally using
tab-completion, so the slash may appear in either superproject or
submodule URL. So, ignore the trailing slash if it already exists in
the superproject's URL, and don't record one for the submodule (which
could itself have submodules...).
