How do we preserve ALL comments?

[IAMtheIAM]

I tried changing specialComments to 0, 1, and all and it had no effect. It kept the special comments.

How do we tell it to keep all comments?

I found the README misleading on this point. I got it working with cleancss -O1 'all:on;specialComments:0' [...]. So the optimization flags are not mutually exclusive. Even if you want level 2 optimizations, you need to set specialComments with the -O1 option.

Got it:

cleancss -O1 'specialComments:0' --output style.min.css style.css

I noted it O1 (o-one) not 01 (zero-one), it so wired to use this lol

@l2aelba - I've updated docs to make it clear what character needs to prefix optimizations level.
