Yeah.

If this is generally annoying I guess I can rejig things to use --cc-cmd
instead, somehow, but it was very convenient because it meant the
machinery which split up the commits could also compute the Cc list at
the same time without having to record it separately, but I assumed it
was routinely done from the number of Cc: trailers already in the kernel
tree...
