L.S.,
The code donated by Dan Keshet has been integrated. You can find it in the
Quick bar under the name ''watch page links". Not a very good name, but I
couldn't think of a better one that would fit.
I have also optimzed the SQL for the what-links-here page for the new
linked/unlinked tables.
Finally, I added some code to the watchlist page to deal with pages on the
watch-list that no longer exist. A remaining problem is that users cannot
delete such pages from their watch list.
