Find the *last* sourceMappingURL in the source document.

[mprobst]

This fixes odd behaviour for source files that contain the literal string
'//# sourceMappingURL=' somewhere in the actual source code.

@evanw ping?

[julien-f]

I am no source map expert but I believe source maps can be specified anywhere in code and can perfectly be defined at the top of the file.

Is #58 enough for your issue?

[mprobst]

@julien-f this actually supports having multiple source mapping URLs in one file, it just changes the behaviour to always use the last one. As transpilers usually append a source mapping URL at the end of the file, the last mapping URL is much more likely to be the right one to use. So I think this change is still useful.

The change to not find quotes might be correct (though I'm not sure quotes need to be escaped in URIs/URLs) and help, but if somebody has code handling e.g. ... sourceMappingURL=http://base/" + myHref, it won't help, so this should still go in.

[julien-f]

It makes sense.

I think it should be mentioned in the README and maybe we should update the examples to have the directive at the end?

[mprobst]

@julien-f done, please take another look.

[julien-f]

LGTM but I don't understand the test: I see only one source map directive, am I missing something?

[mprobst]

Added a clarifying comment - the test driver function actually adds the secondary sourceMappingURL comment.

Thanks for the review, merging this now.
