Yes, should be clean files.

That should be RSN 8)

No, it's just that if it had been a local build I'd have just asked if you'd
confirm that your source code was all in sync.

It starts at the top and works through an entry at a time, IE no special
ordering, this is one of those it's only done rarely, so performance is not
critical.

From what I can tell of the code it's doing the right thing. (well it looks
to be, hence me asking for more details etc 8)

Could you send-pr this?
