Change sourceMappingURL comment syntax to avoid IE JS conditional compilation issues

NNTP-Posting-Host:  89.78.248.150

This is sth that came up a couple of times in jQuery, see:
http://bugs.jquery.com/ticket/13274
http://bugs.jquery.com/ticket/13776

Using syntax like:

    /*
     //@ sourceMappingURL=...
     */

is cumbersome. How about allowing:

    /*@ sourceMappingURL=...*/

or choosing a different symbol than `@`, one that doesn't cause JS conditional compilation issues in IE?
