I stand by what I said, except that I now understand that it's the 
behavior of RET that was changed.  But that doesn't change the fact that 
C-o was initially meant to optimize redisplay by creating some blank space 
before filling it.  See below:

What do you think of these two suggested changes to EMACS?

1) Make Altmode not be ignored when it terminates a search, so that it
would still function as a Metizer.  Some other character would have to
be provided instead as a way of terminating a search and doing nothing
else.  C-D was suggested, but I don't like it.  I'd like to hear other
suggestions.

2) Make C-O do what C-A C-O Tab does now.

3) Also, how many people now find it useful or desirable that Return
eats up blank lines?  This feature was invented in the days when
terminals did not have insert/delete line.
