PATCH: suggestion for completion lists

[Sven Wischnowsky <wischnow@informatik.hu-berlin.de>]

[I forgot to say... that last patch I sent may be offset, due to this
one here.]

I /think/ this was asked for before and personally I really like it:
this makes completion lists obey the NUMERIC_GLOB_SORT option. I.e.
if it is set matches with numbers in them are sorted in a better
vgrepable way.

Question is if this should use its own option and, if not, if we should 
document it. I guess we should, but where: at the option description
or somewhere in the completion docs?

Bye
 Sven
