Not that I care much but you might not want to call it "new". People get
upset when their syntax aware editors get confused by C++ keywords 8)

This should also set the baud bits back in the termios struct
accordingly.
if (tty_termios_baud_rate(new))
tty_termios_encode_baud_rate(new, baud, baud);
Not a big deal and could certainly be a follow up patch after it's merged.
