[PATCH v2] submodule: prevent warning in summary output

From: brian m. carlson <sandals@crustytoothpaste.net>
Date: Aug 20, 2013, 00:26 UTC
Message-ID: <1376958397-800967-1-git-send-email-sandals@crustytoothpaste.net>

When git submodule summary is run and there is a deleted submodule, there is an warning from git rev-parse:

  fatal: Not a git repository: '.vim/pathogen/.git'

Silence this warning, since it is fully expected that a deleted submodule will not be a git repository.

I hesitated to add the test for $status because it will end up having no effect since we exclude that case later. However, for correctness, I included it.
