It seems a little cleaner to have nil specify the current fontset rather
than fontset-default, but only a little.  In your estimation, is there a
significant amount of outside code (e.g. user customizations) that rely
on the old behavior?  If so, I don't think it's profitable to make this
change.

As Miles mentioned, either way this needs to be documented in the
docstring.
