This is a bit buried if one simply searches for fit-window-to-buffere.

I got into this when I discovered that with Emacs 24.1
Electric-pop-up-window does not behave anymore as expected. It uses
fit-window-to-buffer for possibly grabbing the whole frame. In the
context of what Electric-pop-up-window wants to achieve this is a
reasonable and documented behavior.
Possibly there is more code that relies on the old behavior.

But I agree that it is probably cleaner if functions such as
Electric-pop-up-window implement this old aspect of
fit-window-to-buffer in some other way.
