Also, I'm not sure that's what we want to do: as I argued in my previous
message, this change is mostly meant to better fit the behavior of
resize_mini_window, and that behavior applies to all mini-windows,
regardless if they're used for a minibuffer or something else.

I suggest we keep the code as is for now, and we'll consider what to do
*if* someone encounters a regression (which, for all we know, could
also affect the minibuffer case).
