strict mode not detected if under a comment

[johnsonw]

Strict mode is successfully detected when it is at the very top of the file but if you have a comment before it strict mode will not be detected.
Works:

'use strict';
// This program ...

Does not work:

// This program ...
'use strict';

This can be remedied by adding an 'm' modifier to the end of the regular expression in detectStrictMode.js:

/^\s*(?:"use strict"|'use strict')[ \t]*(?:[\r\n]|;)/gm

You're right, and your fix is probably sufficient. But afaik that would detect even wrong uses of "use strict" as legitimate.
