None, I think.  split-window-preferred-function is split-window-sensibly
in recent emacsen and split-width-threshold is 160 by default which fits
my screen resolution and habit to have one fullscreen emacs frame.  So
when emacs splits, I get two side-by-side windows, each about 80 columns
wide.

That tells emacs that split-window-sensibly may only split a window
horizontally (i.e., into two side-by-side windows) if the window being
split is at least 1000 columns wide.  Basically, you ensure that
horizontal splits will never ever occur unless you have a screen that's
5 meters wide. :-)

Instead of the lambda, #'pdf-tools-deactivate-strip will also do.  And
aside from that, this function is undefined in my (the current MELPA)
version of pdf-tools...
