[PATCH] emacs: Added "is:<tag>" style completion to notmuch-read-query.

[Mark Walters]

Hi

> From: Charles Celerier <cceleri at cs.stanford.edu>

> The notmuch-search-terms man page states that "tag:<tag>" is equivalent
> to "is:<tag>". Completion for "is:<tag>" style searches is now supported
> in the Emacs interface.

> Amended by David Bremner: combine lexical-let and let into
> lexical-let*

This version looks good to me; it works and passes all tests. +1

Note it does not apply to master but only needs a tiny fixup (see below)

Best wishes

Mark
