'split-window-sensibly' (initially called 'window--try-to-split-window')
was written by Stefan Monnier and was supposed to subsume the
functionality of 'split-window-preferred-horizontally' (written by Juri
Linkov).  Both know more about this issue than I do.

I only recall that initially many people hated the idea that it would
make a window on the right and subsequently set 'split-width-threshold'
to nil (Bug#431, Bug33929).  I'm afraid that changing the default
behavior again may lead to similar reactions even if people who set
‘split-width-threshold’ to nil should not be affected.

So whatever you do here please read the reports on Bug#1806, Bug#3142,
Bug#20189 (unless you have done so already) first and also do a search
for 'split-width-threshold' on emacs-devel.

Thanks, martin
