Yes, that would be the bug I was trying to address in m4-1.4o/CVS head
when I brought up the issue on gnulib.  m4-1.4.x has a different bug,
where it prints "file:line: m4: message" (oops, it should have been
"m4:file:line: message").

I've been meaning to add something like verror_at_line(status, errnum,
file, line, format, va_list) to gnulib, and use that, rather than using a
homegrown program-name formatter; that would obsolete your proposed patch.
 But thanks for keeping me on my toes.
