Example to reproduce the bug.

If both `sourceURL` and `sourceMappingURL` are set in a script, the mapping is not used.

To reproduce:
- Unzip the attached project.
- Host it by executing 'python -m SimpleHTTPServer 1234'
- Go to <a href="http://0.0.0.0:1234">http://0.0.0.0:1234</a>
- Open the Web Inspector Console (option-cmd-C)
- Look at the first error

Observed:
- The error is reported as originating from app.js:3

Expected:
- The error is reported as originating from app.coffee:1

Notes:
While adding `sourceURL` in this case is not necessary (the script was not generated), it should also not break the source mapping.  Removing the `sourceURL` from `app.js` will lead to the expected behavior.</pre>
