3 improvements:  1. When processing a bundle that contains this source, the search for +sourceMappingURL=     can get a hit on this source itself, causing the source maps to fail to load.  Add a whitespace     checker to the match expression to avoid this case.  2. Avoid checking against <anonymous> fns, as these are not ever mapped in source and     cause an HTTP 404  3. In the case where the sourcemap library loses the name of the function, supply it back     with a brute force expression.
