bug#19576: write-file writes the wrong buffer

> We could run both types of hooks, couldn't we?

As I said we do that already for splitting and deleting windows.  So we
obviously could.  But this means that packages run the same function
twice because they are used to run the same function in both hooks.

‘window-configuration-change-hook’ shouldn't run since the window
configuration does not change.

It won't break anything.  But why should we OT1H make
‘window-size-change-functions’ more efficient when OTOH we call it after
we already called ‘window-configuration-change-hook’?
