[PATCH 1/6] test patch hunk editing with "commit -p -m"

[Benoit Pierre <benoit.pierre@gmail.com>]

Add (failing) test: with commit changing the environment to let hooks
now that no editor will be used (by setting GIT_EDITOR to ":"), the
"edit hunk" functionality does not work (no editor is launched and the
whole hunk is committed).
