Calling $(document).off(".anything") causes stack blowup aftere loading dropdown

[BJTerry]

In b5ad506 changes were made to bootstrap-dropdown.js which resulted in this (essentially):

$(document).on('touchstart.dropdown.data-api', '.dropdown-menu', function (e) { e.stopPropagation() })

being changed to this:

$(document).on('.dropdown-menu', function (e) { e.stopPropagation() })

As far as I can tell, you aren't supposed to call .on with a bare namespace as the event name. If you later call $(document).off(".anything") it causes a stack blowup, as the event object in jQuery has an entry with a key of "" which is then treated as a boolean for determining whether to recurse. This looks like a typo in light of the other changes one can see in the file. Here is a minimal example: http://jsfiddle.net/DFyEr/
