Fget_largest_window returns the largest window and B could be that
window.

With `split-window' the new window is the lower one, we would lose all
associations for B if we did that.

David: Could you set that for the buffer of your window B and look
whether it gives good results.

Earlier I thought about splitting obey a buffer-local value for
`split-height-threshold'.
