Oh, sorry.  I hadn't realized that this is actually a new feature.  :)

Me neither.  Perhaps we should try to make Emacs 23's default
behavior identical to that of Emacs 22: as this bug report shows,
it's not immediately obvious that the windows get split this way on
purpose, and changing the default split will confuse the user if
she's used to look for the new window at a given place.  Old habits
die hard.

Luca, what do you think?
