I do not see the usefulness  of colouring the comment delimiter separately 
(because that
affects all comments in the same way, no distinguishing feature whatsoever ).  
We can keep
highlighting with a back-quote for things that can be evaluated (e.g. 
`something') and 
use single-quote for more general case that allows spaces (e.g. 'this and 
that').

We should not use multiple comment characters (e.g. ;;; Something) because 
those are
for outlines - something of a completely different orthogonal purpose.
