* main.c (complete_command): New command, from Rick Sladkey

	<jrs@world.std.com>.
	(symbol_completion_function): Don't declare rl_point and
	rl_line_buffer; they are now declared in readline.h.
	(show_commands): Don't declare history_base; it is declared in
	history.h.
	* command.c (lookup_cmd): Don't delete trailing whitespace.
