This Hover Cruft is Full of Ills

Recently I spent time refactoring much of the event system in jQuery for version 1.7. Since we added some new event methods as well, I took another pass at the event-related documentation. It was an opportunity to rewrite the pages in a way that make more sense (at least, to me ) and eliminate things that were important five years ago but not so much today. Just like code, documentation accumulates its own cruft over time. I also find that when things get ugly or inconsistent in the code, they often get ugly or inconsistent in the documentation as well. Here's an example: In jQuery 1.4.2 we started allowing people to use the "hover" event name for the .live() and .delegate() methods. This is the equivalent of attaching a "mouseenter" and "mouseleave" event to an element. Really. That is all it does. If you said $("button").bind("mouseover mouseleave", myFunc) you can now say $("button").bind("hover", myFunc)
