Yes, but that's the last part of what I wrote: "then we decide what to do".
And, a priori at least, that decision is the same anytime a window is resized.
IOW, a priori there is nothing special in that regard about fitting a window to
a buffer.

I don't know, but that question is a general one and independent of _this_
bug/feature, which is fitting a window to its displayed buffer.

You are bringing in extraneous stuff.  Interesting stuff no doubt, but not
specific to fitting a window to its buffer.

No I don't.  No doubt window experts such as Martin have some ideas and have
already considered the question.  My point is that it is outside the scope of
this thread.  _Any_ time a window is resized the questions you raise are
pertinent - they have nothing in particular to do with _this_ resizing of a

I repeat.  I don't see why this resizing is any different from any other window
