Subject: [PATCH] Add basic test-script for git-submodule

From: Lars Hjemli <[email-masked]>
Date: Sun, 27 May 2007 22:34:59 +0200

This test verifies the basic operations in git-submodule, i.e. that it is
able to clone and update a submodule repository, that its status output is
sane, and that it errors out when the submodule path is occupied during
init.

Finally the test-script emerges. Btw, thanks for fixing my broken submodule
patch :)
