Should be never.  It is just defensive programming to have a default
label for switches.  This guards against circumstances like someone
changing isc_commandline_parse() to return some other special
character that named was not similarly changed to recognize.
(Extremely unlikely, yes.)  Also, some compilers/linters will warn if
a default case is not present.
