that was fast.

IIRC the  previous  default was quite on purpose:

It's not only for a non-existing command that you get a bogous help buffer,
and in some of other such cases, the user should be able to see and
read what the bogous buffer contains.
(and also note that error messages by in other languages than English,
so you can't just grep for the
kind of error message,...)
