Subject: emacs: add notmuch-address-post-completion-hook
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=343534d82dc8882b3f0e2a847ee9d10ba5392809;p=notmuch.git

emacs: add notmuch-address-post-completion-hook

This hook can be used to update the message based on the results of
address completion. For example using message-templ or gnus-alias to set
the From address based on the To address just completed.

The post-completion command is added to the notmuch-company backend to
ensure that the hook is also called company completion is started
without going through notmuch-address-expand-name. See the docstring of
`company-backends' for more information.
