[PATCH] emacs: Make the queries used in the all-tags section

[Austin Clements]

Out of curiosity, what use cases do you envision for this?  So far
I've only heard two, both of which seem like great ideas, but neither
of which require such a heavy-handed solution: displaying unread
counts for tags rather than total counts, and hiding unused tags.

I would argue that we *always* want to display unread counts (maybe in
addition to total counts, or maybe not).  In fact, I'm generally
surprised by how little notmuch treats the "unread" specially, given
how important that tag is to the user.  For example, I would similarly
find unread counts in the search results far more useful than the
count of messages matching the query.

Hiding unused tags also seems like a genuinely useful feature, and
could be accomplished with a very simple customization UI (perhaps
even linked directly from the hello buffer).

It seems to me like anything more sophisticated is better suited to a
saved search.
