User:Quarl/watchlist.js

// User:Quarl/watchlist.js - adds buttons to watchlist: "unwatch", "diff

// since"

// UNWATCH button asynchronously unwatches and crosses the entry off the

// watchlist.

//

// DIFF SINCE button shows differences since last edited.

// quarl 2006-01-09 added asynchronous feature.

// quarl 2006-02-03 factored; added diff since.

// requires: wikipage.js, util.js, wikiwatch.js, diffsince.js

// originally based on http://en.wikipedia.org/wiki/User:Omegatron/monobook.js
