Since the introduction in REL_1.6 in 2006, the e-mail notification message body template remained unchanged. Now it is possible to improve the message template by using newer internal variables. (Module UserMailer.php could be deliberately modified accordingly, so to skip calculation of the now-unneeded variable $PAGETITLE and $PAGETITLE_URL)
I also added a direct link for action=unwatch in the mail footer which helps users to immediately stop watching without visiting that page (in case they want to stop further notifications for that page).
