terminal: don't assume stdin is /dev/tty
read_key_without_echo() reads from stdin but uses /dev/tty when it disables echo. This is unfortunate as there no guarantee that stdin is the same device as /dev/tty. The perl version of "add -p" uses stdin when it sets the terminal mode, this commit does the same for the builtin version. There is still a difference between the perl and builtin versions though - the perl version will ignore any errors when setting the terminal mode[1] and will still read single bytes when stdin is not a terminal. The builtin version displays a warning if setting the terminal mode fails and switches to reading a line at a time.
