Ah, indeed. But I've never used any of those. It's the OP who asked for 
customizable variables.

More standard faces, e.g. for regexps... maybe numbers as well. If we 
look at "modern" editors, I'm sure there are others we could add.

And then we might need to rethink which faces apply to which tokens. 
E.g. in ruby-mode we apply font-lock-type-face to both class names and 
constants (because the former is a subset of the latter), and 
font-lock-constant-face to :symbols.
