I can by setting split-height-threshold to nil, but then it will never
split vertically.

The current implementation first tries to split vertically. If it fails, it
tries to split horizontally then it
falls back to vertical splitting.

So to split horizontally, it must first fail to split vertically.

The default threshold values are fine. I just want the default behavior to
try the longest edge first.
This way when both splitting would have succeeded (according to their
respective threshold value) it will split first where there is more room.
