(Phew!  I thought you were being a bit daft…I guess I’m a bit too used
to work e-mail.)

Yes.  Even though I prefer the Vi way of doing this (not because it
makes a lot of sense, but because it’s what I’m used to), having
access to this command alone is reason enough to make the switch.
Perhaps I might finally do so.

Here’s a possible solution that seems to work, but probably doesn’t
take some edge case into account:

(evil-define-motion evil-paredit-forward (count)
  "TBD."
  :type inclusive
  (if (and evil-move-cursor-back
        (eq last-command 'evil-paredit-forward)
        (= count 1)
        (not (eolp)) (save-excursion (forward-char) (eolp)))
      (forward-char))
    (dotimes (i (or count 1))
      (paredit-forward)))

Comments?

Thanks!
