[PATCH] Make git-send-email aware of Cc: lines.

["J. Bruce Fields" <bfields@fieldses.org>]

In the Linux kernel, for example, it's common to include Cc: lines
for cases when you want to remember to cc someone on a patch without
necessarily claiming they signed off on it.  Make git-send-email
aware of these.
