 Yes (although as part of a change which would also remove the ambiguity in
 that case).

 My intention is to modify the code which calls match_option()
 (set_option() and check_string()) to record which options are matched. If
 one option is a prefix of all of the others, the string will be considered
 to unambiguously match that option. If the match is ambiguous, we now have
 a list of which options matched, which can be used for the error message.
