[PATCH 18/18] XCOPY: Add help

[Ann & Jason Edmeades]

Er... I have just managed to get git send-email set up and working, and it
would appear to be a feature of it. I do get one question which I answered n
to, perhaps I should anser yes to it and see what happens :-)

Anyone else using git send-email want to comment on how to avoid this?

Thanks!
Jason
