Sorry there was a little error (I forgot the true-part in the regexp for
message.el). Here is the correct patch (the other one again so it's more
convenient for the one who commits)

Here something for the changelog:

2003-02-25  Karl Pflästerer  <sigurd@12move.de>

	* message.el (message-cite-prefix-regexp): added `:' and `#'

	* deuglify.el (gnus-outlook-deuglify-cite-marks): added `:'
