Subject: [PATCHv7 3/6] test-lib-functions.sh: teach test_commit -C <dir>

From: Stefan Beller <[email-masked]>
Date: Thu, 8 Dec 2016 13:03:26 -0800

Specifically when setting up submodule tests, it comes in handy if
we can create commits in repositories that are not at the root of
the tested trash dir. Add "-C <dir>" similar to gits -C parameter
that will perform the operation in the given directory.
