[PATCH 1/4] t4041 (diff-submodule-option): parse digests sensibly

`git rev-list --max-count=1 HEAD` is a roundabout way of saying `git rev-parse --verify HEAD`; replace a bunch of instances of the former with the latter. Also, don't unnecessarily `cut -c1-7` the rev-parse output when the `--short` option is available. Signed-off-by: Ramkumar Ramachandra
