Re: want user option for pop-to-buffer to split window horizontally not vertically

[Richard M. Stallman]

    So now I see that not including it to the next release would be a big
    mistake.  More and more people have wide-screen monitors, and hardwiring
    the current default is very annoying for them.

I really don't want to add new features.  Sometimes I agree to
redesign new features so that don't get their first release in
suboptimal form.  And sometimes I agree to fix a bug in a way that
includes a new Lisp-level feature, because there's no other way.

But I try to avoid that when it can be avoided, and this is an
occasion when it can be avoided.
