bug#1806: dired-pop-to-buffer in wrong place

[martin rudalics]

> Could you also fix Proced and Calendar?

I suppose you mean the call in `calendar-basic-setup' here.  In this
case you probably want to split the largest or LRU window vertically
even if your customized settings would imply a horizontal split.  But
you don't insist on splitting the selected window.  Right?

Any opinions, Glenn?
