_path_files in numeric order

[Christian Neukirchen <chneukirchen@xxxxxxxxx>]

Hi,

I was looking into how to make plain file name completion order "by
version", ie. "foo1 foo9 foo10" and found this to be missing from the
"file-sort" style.  I think the easiest way to add this is to put

  [[ "$tmp1" = *numeric* ]] && sort="${sort}n"

in _path_files, below the *rev* and *follow* things.

If anyone has a less invasive method, please tell me.  Else, I propose
to add this feature (or alternatively, a way to inject own sorting
flags directly).

Thanks,
