I already commented on github on the patch itself, but I want to add
to what Daniel said above - we use Git at work, and although Git
itself tries to support history tracking with renames, it can never
work truly well. What happens in practice is that you suddenly have a
short history (for 'git log' and tons of other commands), and then
you'll have to try combinations of -M and -C and hope that you can get
to the historic info you need. The one thing I have learned to regret
and avoid is massive renames and moves, it only creates grief. And
yes, forget about applying existing patches in a general way.
