Re: Change sourceMappingURL comment syntax to avoid IE JS conditional compilation issues

I'm pretty sure (open to correction) that //@ sourceURL is a Firebuggism introduced to allow annotation of evals. The notation propagated because it's useful.

cc'ing Honza (aka Jan Odvarko) for confirmation.

Not sure how prevalent //@ is in the wild. Probably not very if IE chokes on it.
