/* Extensions/incompatibilities:
   o - BSD output has filenames at the end.
   o - BSD output can appear in different radicies.
   o - SysV output has less redundant whitespace.  Filename comes at end.
   o - SysV output doesn't show VMA which is always the same as the PMA.
   o - We also handle core files.
   o - We also handle archives.
   If you write shell scripts which manipulate this info then you may be
   out of luck; there's no --compatibility or --pedantic option.
