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. > Regards > Rohit >
