enhancement to the emacs "query-pr" command

[Mel Hatzis]

A colleague at work came up with an enhancement to gnats.el
so that query-pr will accept both space separated PR numbers
as well as GNATS query expressions as input.

Please review (and hopefully accept) the attached patch
which, IMO, makes the 'query-pr' command in emacs mode
more intuitive and easier to use.

        * gnats.el (gnats-do-query): Accept a list of PR numbers as an
                  alternative to just a gnats query expression.
