create alias skull_cap -> skullcap
According to Wikipedia, the spelling is without space. This is an umbrella term for types of tight-fitting brimless hats such as beanie, kippah, kufi, zucchetto, etc.

This should imply hat if you are in favour of its existence. I think deprecation is better option for those who aren't.
