Merge branch 'rv/send-email-cc-misc-by'

"git send-email" learned to grab address-looking string on any trailer whose name ends with "-by"; --suppress-cc=misc-by on the command line, or setting sendemail.suppresscc configuration variable to "misc-by", can be used to disable this behaviour. This is a backward-incompatible change that may surprise existing users. * rv/send-email-cc-misc-by: send-email: also pick up cc addresses from -by trailers send-email: only consider lines containing @ or <> for automatic Cc'ing Documentation/git-send-email.txt: style fixes
