I flagged the problem of empty scratch buffer on Feb 13 2008 [1]. This 
means that a few hours before someone patched Emacs to reach that new 
behaviour.

So, does this mean that Emacs at that time was not in pretest phase?

If I remember correctly 22.1.91 has the empty scratch buffer but 22.1.90 
not.

I think that if Emacs was in pretest on Feb 13, than, since that time, 
one had to object on the new behaviour (empty scratch buffer), not only 
now that the acient behaviour has been restored.


Cheers,
    Angelo.
