bug#40506: 26.3; vc-log CVS commit message includes "Summary: "

[Morgan Willcock]

When creating a CVS commit through VC the commit message will include
the literal text "Summary :" instead of treating the field as a
header. From a quick search it seems this was introduced for version
24.4, but the fix for a related bug report looks to be specific to
Subversion.

Related previous bug:
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=18954

...and the patch which changed the behaviour for Subversion:
http://git.savannah.gnu.org/cgit/emacs.git/patch/lisp/vc?id=a59071372884552279edf9c62bfb1aa558ec6db2

As noted in the previous bug report:

"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?"

I can confirm that the same issue exists, although maybe there should be
better way to opt in or out of the behaviour instead of hard-coding it per
provider?

Thanks,
Morgan
