Regex for matching URLs is not strict enough

[raybooysen]

Hit this today, we're using a package which used the source-map-support package. In their code they have a comment that, to the loader, looks like a source map url. I've opened an issue here:
evanw/node-source-map-support#136

Is it possible to make the regex more strict?

@raybooysen Maybe fixed by #31, I reopen if it shouldn't be the case 😛
