ToothyWikiInternals/ListsOfLinks

The following seems to be undocumented UseModWiki functionality:

Action: links: produce full list of all existing links
Action: links&url=1&inter=1: produce full list of all existing links, including external and interwiki links
Action: links&unique=1&sort=1: produce full sorted list of all existing links, mentioning each one once and once only (for some reason, this seems to include nonexisting links too. Oh, well..)
: Fixable by inserting &exists=1 - Action: links&unique=1&sort=1&exists=1 --CH
Action: links&exists=0&editlink=1: produce full list of all UnreifiedLinks
Action: links&search=ToothyWikiInternals: produce full list of all links containing the word ToothyWikiInternals

Also:

Action: index: produce a list of all the pages on the site.
Action: random: produces a random page of the ToothyWiki.

Other permutations of the above work as one would expect.

Saying that, I've had to munge the code for subpages (e.g. ToothyWikiInternals/ListsOfLinks) to work correctly - the original would incorrectly display /ListsOfLinks and a broken link.
