[RFC][PATCH v1] emacs: Improve the behaviour of the 'q' binding.

[David Edmondson]

When a user hits 'q' in a notmuch buffer, kill the buffer only if
there are no other windows currently showing it.
---

This arose from a discussion in #notmuch. Please try it and see if you
like the new behaviour.
