Peter Collingbourne c5e558a80a Remove empty directories when checking out a commit with fewer submodules
Change the unlink_entry function to use rmdir to remove submodule
directories.  Currently we try to use unlink, which will never succeed.

Of course rmdir will only succeed for empty (i.e. not checked out)
submodule directories.  Behaviour if a submodule is checked out stays
essentially the same: print a warning message and keep the submodule
directory.

This test tries to verify basic sanity of the init, update and status
subcommands of git submodule.

. ./test-lib.sh
#
# Test setup:
# -create a repository in directory init
# -add a couple of files
# -add directory init to 'superproject', this creates a DIRLINK entry
# -add a couple of regular files to enable testing of submodule filtering
# -mv init subrepo
# -add an entry to .gitmodules for submodule 'example'
