Ok.  Though it is apparently a regression, I agree it isn't severe,
though a bit jarring.

AFAICS the worst that could happen is the diary (or other calendar
listing generated by using calendar-in-read-only-buffer) being displayed
in two different windows of the same frame, which doesn't seem as bad as
the diary stomping on the calendar.  Or is there another bad effect
you're worried about?

I'm sure it would, but since the only build I have that doesn't show the
issue is from openSUSE of 2014-01-23 and lacks a bzr revno, I'm afraid
this would be quite a time-consuming effort...
