In any case, if the error message required me to look anywhere
outside the patch file, it would make it impossible for me to work.

100% of the time, I just pipe the entire message from MUA to "git
am", and I wouldn't know which line it is complaining if it counted
the long run of mail headers like Received:, etc., because I do not
have such an entire message anywhere in a single file (only my MUA
has it, so I'd need to pipe it to "cat >tempfile" again after seeing
a failure).

Yeah, show-current-patch was a misguided attempt to hide useful
information from the users.
