I think what the patch does is safe in this case; callsites of
apply_patch(), which sets the .patch_input_file field, pass the
string "<stdin>", so you'd say
error: corrupt patch at <stdin>:43
We lost the word "line" in the message, but it would be picked up
rather quickly by users that colon + integer is a line number, so
I think it is OK.

I still do not know if we have a relative-path problem, how severe
it would be if there is, or if it is fixable if we wanted to and
how, though.
Thanks.
