In the discussion I pointed to.  You will have to make a conscious
effort to read just the discussion parts and skip the code attachments
parts.  That's not very easy, but doable: just don't open any
attachments, and whenever you see "diff --git" move one to the next
message in the thread.

Alternatively, Someone™ could re-read the discussion and post the
description of what the posted code did (without showing any actual
code), then you could write the code using only that description,
without looking at the actual code posted back then.  This is a better
method, I think.  Are there any volunteers for the first part, of
coming up with the description?  If no one steps forward, I could do
this myself, but I think this is a good opportunity for someone to
study a somewhat complicated issue related to how the Emacs Lisp
interpreter works.

TIA.
