I mentioned this in the reroll of the patch, but I modified
notmuch-search-show-thread because the return value of
notmuch-show-next-thread depends on it.  In case this is an XY
problem[1], what I want is the ability to go through each email in the
search buffer (like notmuch-show-next-thread does), and when there are
no more messages left I want to call a function.  Changing
notmuch-search-show-thread (and thereby notmuch-show-next-thread),
seemed to be the least intrusive way to do it.
