Hi Tomas,

I just had an idea to make the eepitch accept both the original ^O
(char 15) and the bullet char (char 8226) to indicate its "red star
lines"... can you try this?

  (eepitch-set-glyph0 ?• ?• 'eepitch-star-face)

  (setq eepitch-regexp      "^ *[ •]\\(.*\\)")
  ;; Or: (setq eepitch-regexp "^[ •]\\(.*\\)")

  (defun eewrap-eepitch () (interactive)
    (let* ((fmt   "• (eepitch-%s)\n• (eepitch-kill)\n• (eepitch-%s)")
           (li    (ee-this-line-extract))
           (newli (format fmt li li)))
      (insert newli))
    (ee-next-line 1))

Then try to run this with <f8>s:

  • (eepitch-shell)
  • (eepitch-kill)
  • (eepitch-shell)
  cd /tmp/
  pwd

Now `M-T' will use the red bullet chars insert of the red star
chars...

  Cheers (& hope that the chars 8226 here don't get lost in
  translation),
    Eduardo =)
