Thanks!  Was this bit intentional?

Also, AFAICT the indication (whether in the mode-line or in the echo
area) only shows up once I start repeating a key (e.g. after C-x o o),
not when I first hit a repeatable key (e.g. after C-x o).

Is this intended?  I figure it would make sense to display the
indication before the user starts repeating, since the indication can
serve as a warning that repetition might occur.


At any rate, thanks a lot for working on this.  (And thanks to all for
the addition to diff-hl!)

🤦 Thanks for the heads-up.  IIUC message-subject-re-regexp is used both
by Gnus summary buffers to "canonicalize" subjects in order to only show
them for thread roots, *and* by message-mode to strip cruft before
adding "Re:" to a reply.  I'll need to figure a way to decorrelate those
two uses…

(This is completely off-topic of course; I'm just thinking out loud)
