Description Mark Macdonald CLA 2012-03-16 11:51:16 EDT 
If you supply a grammar that uses a "possessive quantifier":
> ?+
> *+
> ++
> [n,m]+
> {n,}+
> {n}+

... the TextMateStyler should throw an error stating that the expression is not supported. Otherwise you will get a strange error later from the JS engine like this:
> SyntaxError: Invalid regular expression: /a?+/: Nothing to repeat
