I am installing this followup, so that users of verror_at_line with a NULL file 
still comply with GNU Coding Standards by outputting "program: message", even 
though error_at_line currently outputs "program:message" in the same case.

        * verror.c (verror_at_line): Work around glibc bug 2997, so that
        verror_at_line output complies with GNU Coding Standards even when
        file is NULL.
