[PATCH] Completion: Use -B+ in _du

[dana <dana@xxxxxxx>]

Just adding + to the -B spec(s) for du.

In case this seems pedantic: The lack of + causes really irritating behaviour
when completing arguments after manually entering the +-less option and its
argument as one word, as in the following case:

  % du -BM /some/incomplete/path/<TAB>
  completing size (bytes):

A quick search of the other completion functions shows 219 matching /-\w\[.*\]:/
and 67 matching /-\w,--[\w-]+=/. Probably not *all* of those are problematic,
but i bet most of them are. I'll try to go through and fix them all (or at least
the ones i'm most familiar with) some other time.

(Unless it's possible to fix it at a lower level? It seems like _arguments could
be made to handle this mis-spec more gracefully, as long as it hasn't been
called with -w/-W. Maybe that's too 'magic' though)
