Subject: Add basic test-script for git-submodule
X-Git-Tag: v1.5.3-rc0~169^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=88961ef2589433044365213fab98de081a1ce70f;p=git.git

Add basic test-script for git-submodule

This test tries to verify basic sanity of git-submodule, i.e. that it is
able to clone and update a submodule repository, that its status output is
sane, and that it barfs when the submodule path is occupied during init.

+#  -add a couple of regular files to enable testing of submodule filtering
