bug#18954: 24.4; vc-log Summary: header is included in log message with svn

[Ed Avis]

I use vc-mode to edit and commit files in an svn repository.
On running vc-next-action on a modified file, a log message buffer appears containing the
text Summary: and a blank line.  Typing in this buffer adds more text
after Summary:.  On committing with C-c C-c, the literal text Summary:
is included as part of the svn log message, as you can see afterwards
by running 'svn log'.

Please see <http://emacs.stackexchange.com/questions/2717/>
where forum user Stefan indicated that this was a bug (presumably,
the Summary: header should be stripped out when sending the text
to svn) and asked to report it.

bug#18954: 24.4; vc-log Summary: header is included in the log message

	This pseudo-header (along with an optional Author:) is added by
	the log-edit-insert-message-template command, itself called from
	log-edit-hook.  Thus, as a work-around (which I happen to use
	myself), it’s possible to simply remove the function from the
	hook, like:

(eval-after-load 'log-edit
  '(remove-hook 'log-edit-hook 'log-edit-insert-message-template))

	A quick scan through vc/*.el suggest that the Summary: header is
	only recognized by vc-arch.el (which, however, doesn’t seem to
	take care of Author:), while only vc-git.el seems to recognize
	Author: (and doesn’t seem to care about Summary: in turn.)

	If so, this bug actually affects most of the VCS supported by
	the Emacs VC facility, and not just Subversion.

	I believe this behavior is highly inconsistent, and would rather
	suggest either of the following options.

	• Amend the log-edit-insert-message-template function to only
	  generate the template if /either/ explicitly requested by the
	  user (as in: via a yes-maybe-no variable setting, or by
	  running it interactively) /or/ when the headers in question
	  are known to be recognized by the target VCS.

	• Remove the function from the hook’s default value.

	Also to note that log-edit-insert-cvs-rcstemplate apparently
	relies on the existence of CVS/Root to decide if its respective
	template should be added.  My guess is that it should instead
	check the VCS chosen by the user (as in: vc-switch-backend) for
	the fileset in question.

Too quick a scan. log-edit-extract-headers recognizes the Summary header
by default, so the difference must be betwen backends that pipe their
commit message through that function, and those that don't.

Quite a few of those, yes: RCS, SRC, SCCS and CVS must have this
problem, as well as the obsolete MCVS and Arch.

I'm puzzled, however, why hasn't anyone else reported this problem by
now? Maybe nobody uses most of those, but what about CVS? Do its users
just stay on older Emacs versions?

The easiest solution seems to be to teach all VC backends to recognize
it. It would be rather hard for me to test the results, though.

Sorry for taking so long, but this bug should be fixed now, in the
branch emacs-25.

Please test at your earliest convenience.
