Do not send-keys literally by default about libtmux

[ritiek]

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.
