Auto space before and after <= and >= in Swift code

At least in the compiler I am using now (and probably in general as I have seen this being described as an issue in some Swift forums) there must be a space before and after <= and >= (and I assume also < and >; == seem to work without in my compiler though). It would therefore be nice if the editor could automatically add a space before and after if you forget it.

This should also be part of the Prettify functionality I have just suggested.
