Added string-split (which I stole from ediff-util), changed

pop-to-buffer to switch-to-buffer and added message on how
to exit the multi-line-edit mode.

+;; He writes:
+;;
+;; Thanks a lot for the new version of todo-mode.el.  As you will see I
+;; have messed it up a bit, hopefully for the better -- I don't like
+;; short, cryptic names for variables and functions, so I renamed most of
+;; them, and `defalias'ed the old function names.  I hope you don't mind
+;; too much, I just kinda couldn't stop myself.
+;;
+;; Additionally, I included some support for multiline entries, cleaned
+;; up (IMHO :) a lot of the code, included completion-support for which
+;; category to install a new entry in, and possibly some other changes I
+;; can't remember :)
+;;
+;; It's getting rather late, and I have just done some preliminary
+;; testing on whether all of this really works, but so far it looks
+;; good.
