Darren Hart - May 16, 2011, 10:26 p.m.
Rather than sending every patch to every recipient of the entire series when
-a is used, only send the cover letter to everyone and use git's
--signed-off-by-cc feature to generate an auto cc list for the individual
patches.

Add a -c option to use --signed-off-by-cc to auto cc recipeients at the
individual patch level. This is implied by -a.

Using git to harvest the Cc list means only collecting Signed-off-by and Cc
lines, rather than the more generic *-by lines previously. This is a fair
trade-off for significantly reduced complexity. If users want to add Acked-by
and Tested-by lines and want to use the -a feature, they should include those
recipients as Cc lines as well.

Now that we rely on git for auto-cc for the individual patches,
make sure the user is prompted before sending each patch by forcing
--confirm=always.
