Do not send-keys literally by default

[ritiek]

I noticed that libtmux sends keys to a window pane literally. A minimal reproduction:

import libtmux

server = libtmux.Server()
session = server.new_session('happy_session')
window = session.new_window('happy_window')
pane = window.attached_pane

# instead of KeyboardInterrupt, libtmux sends 'C-c'
pane.send_keys('C-c')

tmux uses -l to specifiy if the keys are to be sent literally:

# not literally
tmux send-keys -t happy_session C-c

# literally
tmux send-keys -l -t happy_session C-c

It would be nice if there were an option to override this behavior in libtmux and preferably set as defaults Pane.send_keys(literal=False) just as in tmux.

I was messing around a bit and I think I figured what's going on.

libtmux prefixes the command with a blank space, so special events like C-c become <space>C-c which causes tmux to take it literally.

A workaround for the moment would be to pass suppress_history=False in Pane.send_keys().

The problem still remains about sending keys literally while suppress_history=False.
