PATCH: complete after rpm -q --whatprovides



Long standing gripes that act as displacement activities, latest in a
series.

The rpm manual page says "rpm -q --whatprovides" queries a CAPABILITY.
It neglects to say what a CAPABILITY actually is, but files certainly
work as well as packages.  Using a package is supported, but as far as I
can see the "--whatprovides" is then redundant.

As only absolute paths to files work (I've tested this), I've used the
leading / as a discriminator --- otherwise completion is really slow
because it needs to compile a package list, which is a waste of time for
files.
