What I ended up doing was when I got the full verb name via verb_info, if
that generated E_VERBNF and the verb name was not "", then I assume it's
"huh" and print that.  There are most likely a lot of problems with doing it
like this,  but oh well.

I'd suggest adding another field with the full verb name, but that is a nice
big patch to cover up for a nice big hole introduced with the implemenation
of the huh stack.  The other alternative I see is to call huh with it's
arguments being the entire command line, and not worring about the value of
verb.  This would require only one verb to be changed on most MOOs,

   $command_utils:do_huh(verb, args);

Or, I can just shutup and continue to assume that E_VERBNF means "huh".
