Brutally refactored to boost performance in large-addressbook situations.
2001-03-17 Jon Trowbridge <trow@ximian.com> * gui/component/select-names/e-select-names-completion.c: Brutally refactored to boost performance in large-addressbook situations. These fixes give accepable performance (even with the suboptimal pas-backend-file searching) using tigert's addressbook-of-death. svn path=/trunk/; revision=8793
