Subject: 27.0.50; Improve docstring and customization for 'message-signature'
Date: Mon, 10 Sep 2018 15:12:40 +0200

The manual states

   If you change ‘message-signature’ to ‘nil’, Emacs will not insert
your mail signature automatically.  You can insert your mail signature
by typing ‘C-c C-w’ (‘message-insert-signature’) in the mail buffer.
Emacs will look for your signature in the signature file.

However, the docstring for message-signature doesn't state that nil is a
possible value, and the customization choices also don't suggest nil.

We could even put this in emacs-26.

Fine with me, but if it will go to emacs-26, then the :version tag
should say so.

Thanks.

May as well rewrite it all to use the active voice while you are there.

It's not new, and the default hasn't changed, so a version bump is not
appropriate. It's just a doc fix.

OK. I modified 'mail-signature' as well, it didnʼt describe the nil
value.

To me, "active" would be:

If nil, don't insert a signature.
If t, insert `message-signature-file'.
If a function or form, insert its result.

Thanks; I've now applied this to Emacs 27.1 with Glenn's tweaks to the
text.
