I do agree that the better error message is probably worth the
additional 'test_path_is_file' before the 'test -s'.  Although it may
be better to only make that distinction in the 'if' (and then maybe
just using 'test -f', which would explain better why we have an
additional call.

Either way it would be nice to describe that reasoning in the commit
message, as it's not 100% clear from the code what is going on here,
which also lead to Junio's question.
