Don't worry, I wasn't intending to.  That patch was just for
demonstration.  I suppose it might be possible to have paren overlay
per-buffer, so that the overlay doesn't disappear and reappear all the
time, but I don't think it's worth the complication.  I'm pretty sure it
would remain possible to write a command that's able to observe some
inconsistencies regardless: since show-paren-mode relies on idle-timers,
the behaviour is affected by the timing of the user's keystrokes.  It's
best to write commands that are oblivious to what show-paren-mode does
(e.g., the (cl-some ...) condition I posted in that same message).
