[PATCH 2/2] emacs: make elide messages use notmuch-show for omitting messages.

[Mark Walters <markwalters1009@gmail.com>]

Previously the elide messages code got the entire-thread from
notmuch-show.c and then threw away all non-matching messages. This
version calls notmuch-show.c without the --entire-thread flag so
it never receives the non-matching messages in the first place.

This makes it substantially faster.
