Understood.

The revised patch is upthread
(<https://lists.gnu.org/archive/html/bug-gnu-emacs/2020-03/msg01100.html>)

There are no changes in the patch that are not necessary for fixing the
problem. The ediff changes (only adjusting callers) are necessitated by
moving the helper function to subr-x.el, so that Gnus (or anything else)
can use it, too.

OK?
