patch 9.0.0980: the keyboard state response may end up in a shell command

Browse Source 
Problem:    The keyboard state response may end up in a shell command.
Solution:   Only request the keyboard protocol state when the typeahead is
            empty, no more commands are following and not exiting.  Add the
            t_RK termcap entry for this.
