[Jim Meyering]

Thanks to Arnold for spotting/reporting this bug.

        * src/ls.c (gobble_file): Use stat.st_author, not stat.st_uid
        when computing the --author column width.  This bug might have
        resulted in misaligned columns when using the --author option
        on the Hurd.  Spotted by Arnold Robbins.
