the last two characters of the option name. Only one termcap code is
required: Cursor motion, 't_cm'.
! The options 't_da', 't_db', 't_ms', 't_xs' represent flags in the termcap.
! When the termcap flag is present, the option will be set to "y". But any
! non-empty string means that the flag is set. An empty string means that the
! flag is not set. 't_CS' works like this too, but it isn't a termcap flag.
