commit 071c9ddf7c4b6a0425e45429956b61ccab3c32ad

    CSS.g: fix Decision can match input warnings for rgb() and rgba()
    
    Specifically this warning:
    
    Decision can match input such as "{'\t'..'\n', '\r', ' '}" using multiple 
alternatives: 1, 2
    
    It's because it was trying to match optional whitespace immediately 
followed by more optional whitespace in some situations.
