This is an example of a possible display function. It displays the
count for a search as messages/threads. This will be slow on a large
search but could be useful for a small search.
It also extends and renames the existing (unused)
notmuch-saved-search-count function to count threads if wanted. The
rename is done because the function is not saved-search specific.
