Thanks Dirk and David,

I've just pushed this version (finally!) of this nearly-trivial patch
From so long ago. The bug hasn't been as important lately since by
default notmuch doesn't even display saved searches with 0 results. But
the bug was still present for anyone that set
notmuch-show-empty-saved-searches to a non-nil value.

I've also added a test to the test suite to ensure this case gets
exercised there.

Thanks again,

-Carl
