> To my mind there are two general areas that make wide use of comma-delimited configuration name lists.  The first area is in Ivy file dependency mappings and along with simple configuration names, one can also make use of operators like * for wildcarding and ! for negation.  The second area where these lists are used extensively is in the "conf" attribute of the Ant resolve task and the various post-resolve tasks.  Much like before one can also use the * character for wildcarding here, but much to my frustration the "conf" attribute of these Ant tasks doesn't seem to recognize the ! character as the negation operator.  The attached patch (which includes test case) remedies this tragic situation.
