I'm not sure what you're after here.  If you don't want the matches listed
from $COMPREPLY, why not manipulate the variable yourself?  Why not write a
second function that calls _func, does something with the resulting contents
of $COMPREPLY (e.g., print your formatted list of suggestions), then remove
all the unwanted elements from the array before returning?  For instance,
you could empty the array if there is more than one possible match.

Since the -o default option is in effect only when the other completions
return no matches, this would seem to satisfy your requirements.
