[PATCH 0/2] More git-send-email updates

To follow up on some conversations related to git-send-email this week, here are two updates:

The first adds a command line option to suppress adding the "From" address to the list of addresses to Cc, when it appears in a From: header line. (Note that git-send-email never looked for From: lines inside the body of a message to use as a source for Cc: addresses, which, given the patch formats Linus has previously talked about, is probably a bug.)

The second patch adds the mythical "--cc" option. I say "mythical" because it has never existed, but both Junio and I have mentioned it (or used it) recently, so we both *assumed* that it existed. I think that's justification for adding it.
