Suppressing auto-cc for specific addresses

Hi,

I'm looking for a way to suppress certain Cc: fields that are normally 
automatically added for addresses mentioned in Cc: lines found in patches.

In particular, the kernel rules for marking patches for stable release 
inclusion wants users to add a "Cc: stable@kernel.org" line in the patch 
itself but to not actually send a copy of that patch to that address. It 
will be picked automatically once the patch was applied upstream.

I couldn't find a proper way to do that with git send-email, so I dare 
to come up with a patch proposal. Is that acceptable or is there any 
better way (which I'm not aware about) to achive this?



Thanks,
Daniel
