If any of these errors are false positives, please file a bug against check-webkit-style.

OK, it's not that simple it seems. Apparently --find-renames can guess some renames wrongly. There is already a discussion related to why this was explicitly disabled in bug 48075. In any case, right now patches moving files that are generated from diff are really hard to review, so I think we should aim to fix this somehow eventually.

I think this has become obsolete due to GitHub. But please reopen if you disagree.
