[PATCH] fix "git-submodule add a/b/c/repository"

[Sylvain Joyeux <sylvain.joyeux@dfki.de>]

The 'master' version of git-submodule.sh fails to see that
a/b/c/repository is an already existing repository and messes up the
whole thing. The following patch fixes that.

Subject: [PATCH] fix submodule add for non-toplevel in-project directories

This patch fixes git-submodule add for submodules that
already exist in the current package tree, in a folder
which is not at toplevel, i.e.:

  git submodule add a/b/c/repository
