[PATCH v4 0/3] send-email: add --header-cmd option

Hello,

This v4 drops the copyright hunk as suggested by Eric, and adds a
 --no-header-cmd as suggested by Junio.

Thanks you!

Maxim Cournoyer (3):
  send-email: extract execute_cmd from recipients_cmd
  send-email: add --header-cmd, --no-header-cmd options
  send-email: detect empty blank lines in command output
