Hi,

There's a new search query syntax in Gnus, in Emacs master, in a library
called gnus-search.el. This library allows contact management packages
to add auto-completion for contact names/mail addresses during search
query entry: for instance the user could type "from:eri<TAB>", and that
would complete to "from:[email protected]".

The attached patch checks to see if the library is present, and adds
bbdb-hashtable to the contact tables if so. It might be desirable to
create a specific completion table just for this, but I expect just
using bbdb-hashtable directly will be fine.

Thanks,
Eric
