Subject: emacs: Improve the behaviour of the 'q' binding.
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=30f1c43efe32c83193a6b9ae1f31ab2667e4195d;p=notmuch.git

emacs: Improve the behaviour of the 'q' binding.

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