Subject: bug#72341: VC: CVS template lines not stripped when committing
Date: Sat, 8 Mar 2025 15:06:50 +0100

I've tested Mauro's patch and it works fine for me.

I've also checked out the behaviour in the help-mode buffers and that
seems more difficult to address.  I'll handle that separately.

I think at this point it is not really worthwhile to split Mauro's patch
out into a separate bug report, unless you guys give a good reason to do
so.
