If a user attempts to move a page to the same title, he sees the error message selfmove (Source and destination titles are the same; cannot move a page over itself.). This can be avoided by disabling (graying out) the "Move page" button until a different name is entered.

Will do soon.

Do we /ever/ disable buttons in JS? I don't think so, the save page button isn't grayed out if the page hasn't been edited, for example, so why is this a special case? If the user submits invalid input, they get an error message, I don't see what the problem is. Marking as an enhancement, because it is, but I'm not sure whether it makes sense to start disabling buttons.
I agree. While it seems wrong to allow submission for a null action that results in an error. I think disabling the button would be even more counter-intuitive as it isn't obvious the button will enable once you start typing. It might lead the user to believe the page can't be moved for an unknown reason. This is imho not an established UX concept on the web and certainly not within MediaWiki at this time.
