It is possible to make categories contain themselves (eg Category:X can contain Category:X in a list of its own members - the link works, clicking it takes you to... Category X). This seems a rather silly thing to make possible; this bug is asking for such nonsensical categorisation to be ignored when the category page is displayed, so that if Category X does contain the code "[[Category:X]]", it doesn't do anything. You might say "well categorising a category in itself is a silly thing to do, so just don't do it" - but if you have a template that automatically categorises into a category, and you want to display that template in the category, you need to add special collision detection just because this silliness is possible. Removing the silliness would make life quite a bit simpler, templatewise.
I would want to make very sure that nobody wants the current behaviour before changing it. Examples of possible uses of this: *Having category:Hidden Categories be in Category:Hidden Categories if its hidden. (Ok, ignoring tracking categories, I really can't think of anything else, but maybe somebody else has)
Satirical wikis like self-containing categories, I don't think you will find one without. For example: * http://uncyclopedia.wikia.com/wiki/Category:Self-reference * http://kamelopedia.mormo.org/index.php/Kategorie:Re%28h%29kursion
Well, maybe we can add some additional "no really, this category SHOULD include itself" mechanism.
