Thomas: Any further input on this?  If I understand you correctly,
you're not saying that there's anything wrong with Tom's patch, just
that you would like to do some further hacking afterwards.

Tom: CFbot says this patch doesn't apply anymore.  Could you please
rebase?  Also: There's further input from Movead; his proposed test
cases might be useful to add.
