non namespaced selectors are getting compressed with skin compression turned on

Selectors such as:

.AFSelector

{ ... }

was getting rendered in both compressed and uncompressed way with compression turned on.

But this was not happening for

.AFSelector af|foo { ... }

af|foo.AFSelector

{ ... }

This was rendered as compressed with compression turned on.

The solution is to render the non namespaced selectors only in un compressed format.
