This patch adds a -h argument to send-keys. It is intended for control mode
to avoid any running into problems with transmitting certain bytes over a
transport with inband signaling (e.g., telnet) or for sending special keys
that the terminal driver might affect (like newlines). Example usage to
send ^]:
send-keys -h 1d
