I'm trying various completions after customizing completions-sort to nil,
so currently noticed a problem in the completions of file names.

'readdir' returns the order of the file system,
and 'file_name_completion' reverses it.

This means bringing 'Qcompletions_sort' to 'file_name_completion'?
Probably not worth the trouble. Better to declare the value nil of
`completions-sort' as unsupported.
Anyway this was just an experiment to see how useful is the
no sorting option for completions.
And the conclusion is that it's useful only for part of completion types,
and not useful for others. It's useless for obarray and file names.
