The reason those redirects exist (EG: ParserFunctions → Extenstion:ParserFunctions) is because when you search by name, it won't automatically redirect when they are in a namespace other than the Main, although I have submitted a bug for that to be looked at (25432). Whilst I/we do try to get rid of some of the cross namespace redirects when they get created, we can't exactly purge them all since we can't tell what outside sources point to them that easily and risk breaking links.
