sourceMappingURL from the last file is left over in the concatenated file.

[Eketol]

Hi, I'm concatenating two files: "myapp.libs.source.js" and "myapp.source.js".
Both files contain their own sourceMappingURL.

After concatenate the files, the sourceMappingURL from the last file is included in the concatenated file, so I end up with two sourceMappingURLs:

//# sourceMappingURL=myapp.source.js.map
//# sourceMappingURL=myapp.map

Only the sourceMappingURL from the concatenated file should be included.

I use a plugin for VisualStudioCode called "SourceMapVisualization" and I have to remove the first sourceMappingURL every time, to make it work properly.
