[PATCH] Add a test for git-commit being confused by relative GIT_DIR

It takes an inordinarily large amount of time to create these tests, I
am afraid.  There is little sense in making a more extensive audit,
cranking out more cases which fail with relative paths, when the fix,
namely making GIT_DIR absolute, is so simple.

+It creates a commit-hook and tests it, then moves .git

+and tries commits from the top and the subdir, checking
