It might be worth tailoring the message to the command rather than
having exactly the same message for commit and reset

I think my comments from patch 3 about <pathspecs> and the option names
apply here as well

I wonder if there is a way of calling parse_pathspec_file() from
parse_and_validate_options() instead. Otherwise we end up validating
options here instead which is a bit messy.

The test comments from patch 3 apply here as well I think.
Overall this series is nicely structured and is looking pretty good
