Re: Allow utilizing fragments of the minified file name for map file names

What's the "file:" parameter for? Does any debugger need it? I believe Dart
omits it entirely and it works okay, in Chrome at least. Maybe we should
make it optional?

You might find this interesting: Dart has started generating two js files
(one for Chrome extensions with some extra stuff at the end) and want to
use the same sourcemap for both:
