Long titles break edit permalink box

[ryan]

Edit a post with a long title. Click the permalink Edit button. Ellipses are present in the middle of the slug. Press Save without changing the slug. The permalink is now -1.

Actually the problem wasn't in long titles, the same happened with short ones too :-) The ajax request didn't have a proper nonce, that's why the -1 appeared.

(In [6788]) Fix edit slug ajax nonce. props nbachiyski. see #5816

The ellipsis still end up in the final slug.

In the beginning it was the intended behaviour, but now I realize it was rather stupid. Here is a patch, which shows the whole slug in the edit box.

(In [6794]) Use full slug, not abbreviated slug, when editing. Props nbachiyski. fixes #5816
