Are you sure fit-window-to-buffer was called?  My reading of
calendar.el is that it isn't in this scenario.

See above: are you sure?

I don't see what I need to explain.  From my POV, what we see here is
all normal, as I already explained in my original response to Stephen.

Then you agree with me: there's no problem here, just normal reaction
to the fact that point entered a partially visible line.
