Is this helpful?

Please remove the trailing semicolons.

Please remove the trailing semicolon.

This looks suspicious. Does the result of toImpl really need to be adopted? The function does not have "copy" or "create" in the name.

Not at the moment, but the other UA CSS files have similar comments at the top. I'll remove it.

Done.

Done. C&P from the line below, so I fixed it there too.

I was confused because the other methods in this class that return Strings adopt the result of toImpl - generateFileForUpload and shouldGenerateFileForUpload, even without "copy" or "create" in the name. I've removed it.

I don't know which is correct, but it would be easy to tell from checking the code, or stepping through it. Seems likely that there is something to fix here, if only naming.

Committed r140863: <http://trac.webkit.org/changeset/140863>

Landed with names altered to prepend "create". I forgot to remove the comment in the plugIns.css file, but that will go in the next commit.
