so (%) is to be considered as a string?
in particular everything between ( and ) should be considered as a string?

mhh... probably because your definition comes after the definition of % 
comment?

yes probably this generates a regular expression that's wrong...

Although I don't know postscript I can try to fix this problem.

I'd need an input test file (in postscript) with % used in several 
context, i.e., when it should be treated as a comment and some examples 
of valid postscript strings (for instance, can ( ) strings be nested? 
can ( or ) be escaped?)

hope to hear from you soon
cheers

P.S. yesterday I released 2.6 of source-highlight
