Ah, okay. You are using GNU locate and I am using mlocate.

So _locate is trying to match *(#i)gnu locate*, which does not appear in the
`locate -V` output (nor does it appear in the `locate --version` output).
Does anyone have an older version of findutils handy? Would matching for
*findutils* or (#i)*findutils*gnu* cover all possibilities?

% locate: invalid option -- V
Usage: locate [-d path | --database=path] [-e | -E | --[non-]existing]
      [-i | --ignore-case] [-w | --wholename] [-b | --basename] 
      [--limit=N | -l N] [-S | --statistics] [-0 | --null] [-c | --count]
      [-P | -H | --nofollow] [-L | --follow] [-m | --mmap ] [ -s | --stdio ]
      [-A | --all] [-p | --print] [-r | --regex ] [--regextype=TYPE]
      [--max-database-age D] [--version] [--help]
      pattern...
