Auto close tag doesn't work when typing </ before a non-space character.

[RaymondLim]

1. Open http://codemirror.net/demo/closetag.html.
2. Select all text in there and start typing <em>.
3. Delete </em> that is auto inserted.
4. Type any word and then move the cursor inside the word so that the cursor is immediately followed by a non-space character.
5. Type </.

Result: No auto insertion of em>.
