Ah yes, indeed!  I don't know why I didn't see this when Stefan K made 
that objection.  OTOH, now that I'm using the patch in which there is no 
such delay (except when 'ding' is used), I agree with him that it's better 
to see the error message immediately.  Perhaps this delay is less visible, 
from a psychological viewpoint, with an inverse video flash?

I'm reassured to see that I wasn't alone to err in the darkness of 
ignorance ;-)
