Me too.  I just reread the thread, which is long and is mostly long inline 
patches (ugh).

I'm just assuming at this point that those working on it made a useful 
improvement.

In terms of what I read, I think the main point is for `C-h k' to let you know 
(1) that there are multiple events (when there are), (2) show you the info for 
each of those events, and (3) present them in order of their occurrence.

I think Stefan argued for each of (1), (2), and (3), as did I.

I also think that, if it presents some difficulty, in terms of providing help, 
to deal with both `C-h c' and `C-h k' in this context, then my concern was with 
`C-h k'.  In principle, we should be able to provide good help for each of 
those help keys.  If we can't do that for both using the same or similar code, 
then we should find some way to handle them separately.  What I really care 
about here is `C-h k' help.

If I ever get around to using Emacs 28 (I can't use Emacs 27.1 at all - breaks 
everything I have), and if at that point I have something to say about the new 
`C-h k' doc for this, then I'll send another bug report.

Thanks for everyone's attention to this bug.
