to the superior routine.
- In the case of an ambiguous return (-1), *RESULT_LIST will be set to
- point at the prefix_command (ie. the best match) *or* (special
- case) will be 0 if no prefix command was ever found. For example,
- in the case of "info a", "info" matches without ambiguity, but "a"
- could be "args" or "address", so *RESULT_LIST is set to
- the cmd_list_element for "info". So in this case
- result list should not be interpeted as a pointer to the beginning
- of a list; it simply points to a specific command.
