This fires on "or (at your option) any later version" and variations
thereof, including line breaks after "or" (e.g., blockdev.c).
Also for older files the SVN usernames appear as duplicates.
For SVN and CVS commits we'd additionally have to check the commit
message for whether the committer received the code from another author.

Of the list, 90% seem regular contributors.

I didn't say resolving the issue would be possible in a day. Introducing
more GPLv2-only code will make it even more work though.
