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

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*
