* fhandler.h (fhandler_termios::line_edit): Replace third argument with

Browse Source 
passed-in termios struct.
* fhandler_console.cc (fhandler_console::read): Prior to loop, make a copy of
current termios for passing to line_edit prior so that all characters are
processed consistently.
* fhandler_tty.cc (fhandler_pty_master::write): Ditto.
(process_input): Make a copy of curent termios prior to read for use in
subsequent line_edit.
* fhandler_termios.cc (fhandler_termios::line_edit): Replace third parameter
with passed-in termios struct and use it throughout rather than the data from
the current fhandler_termios class.
