	* command.c: (sort_node) use vector_max instead of referencing
	  (struct vector *)->max directly. Test that vector_max is > 0
	  before using it to calculate an index.
	  Fixup vector loop to make main body conditional on vector slot
	  not being empty.
	  (cmd_cmdsize) Fixup vector loop to make main body conditional on
	  vector slot not being empty.
	  (cmd_filter_by_completion) ditto
	  (cmd_filter_by_string) ditto
	  (is_cmd_ambiguous) ditto
	  (cmd_describe_command_real) Change index integers to unsigned.
	  Test that vector_max is > 0 before using it to calculate an index.
	  Return immediately with CMD_ERR_NO_MATCH if vline has no
	  active slots.
	  Fixup vector loop to make main body conditional on vector slot
	  not being empty.
	  (cmd_complete_command_real) ditto.
	  (cmd_execute_command_strict) Fixup vector loop to be conditional
	  on non-null slot.
