`C-x 0' isn't a command I use much, so I don't really have much
intuition about how it's supposed to work.  But, indeed, playing around
with it, it seems unexpected that `C-x 0' selects a different window
(instead of remaining in the "merged" window).

If I'm reading that patch correctly (I haven't actually tested), that
seems more DWIM to me.  Perhaps Martin has some comments here; added to
the CCs.  (And if anybody else has an opinion here, please do chime in.)
