Description:
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.
