spaces striped when adding category

[ryanduff]

Following up on [3135] and #1882 when adding a new category from the write page (which finally works), the spaces are striped when its added to the list. Example: new category becomes newcategory in the list of available categories. Reloading the write page or viewing at manage > categories shows correctly as new category.

This is trivial, but might worry new users when they add a category and see it show up incorrectly.
