As far as I can see, all the comments were taken into consideration in
this final version of the patch, but it was not applied?

So I've now done so in Emacs 28.1.  The patch didn't apply cleanly, so I
merged a few of the lines by hand.  Please look the results over to see
whether I messed up or not.
