Patch pushed. Thanks everybody.
I'll just go ahead and close the bugzilla tickets. Even though we want
to fix PSR for real and those bugs could be useful as a documentation
of what's wrong, I think it's better to just close them since they're
actually fixed now. We can still go back to them later since they're
documented in the git commit message.
If anybody disagrees, please feel free to reopen them.
