How to get rid of the "Summary: " inserted by vc log-edit.el?

How to get rid of the "Summary: " inserted by vc log-edit.el?

[Steinar Bang]

Platform: emacs 26

Is there a simple way to get rid of the "Summary: " tag inserted into
the comment buffer when making a commit with 'C-x v v'?

The first, and only, thing I do with the Summary: tag is to delete
it. And it would be nice not to have to.

But it doesn't look like this tag is configurable...?  And it wasn't all
that easy to find where it is set either.

The place I've found is set, are:
 When the author field is set
  http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/vc/log-edit.el#n834
 When the Amend header is toggled
  http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/vc/log-edit.el#n1179
 Possibly as a side effect of extracting headers from the commit message...?
  http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/vc/log-edit.el#n1124

Or is it perhaps set in a completely different place?

Thanks!

Hi,
Customize the variable "log-edit-hook" and remove
"log-edit-insert-message-template" from the list of functions there. There
are three functions on the list by default. They can all be removed if you
want, without causing any problems.

Thanks! I will try this!

Why, though? The idea behind it is to use email headers-like interface 
for additional info. Like Author and Amend, for example.

Well, I don't need the additional info don't and want the additional
info.  I don't see what I would use it for. :-)

What I want is to have human readable commit messages with a first line
that are as clear and concise as I can make them (using imperative is a
great tool for this).

VC removes "Summary: " before creating a commit, so you can have said 
commit messages either way.

Hm... I was going to say that the commit is not removed when I commit
with vc.

But then I decided to try it, and "Summary: " was removed.  This is on
 GNU Emacs 25.2.1 (i686-w64-mingw32) of 2017-04-24

"Summary " is also removed on git versioning on emacs 26 on
 GNU Emacs 26.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.5) of 2019-09-23, modified by Debian

"Summary: " is *not* removed when using vc-rcs (I use RCS to version
config files on GNU/linux) and that may be what has confused me.

Or it could be that the interplay between magit and vc-git on occasion
leaves the "Summary: " in place...?  (of course it easy to amend if you
see it before you have pushed, but...).

But in any case I want to lose "Summary: " for RCS where it isn't
removed, so I'll use the config changes suggested in the other post.

That's very weird. I don't see anything in vc-rcs.el that would suggest 
it treats the Summary header differently.

Anyway, maybe file a bug report. Somebody might have a better idea.
