I've finally gotten around to implementing this. Yes, I get the idea,
but there wasn't much I could improve, so I've basically taken your
function and adapted it for use in my package. Works fine for me so far,
and I haven't had any serious bug reports (yet).

I've taken a slightly different approach. I wrote a function that unsets
the margins and then simply calls `split-window'. Since
`split-window-preferred-function' is a user option, it's not installed
by default. I've left that up to the user to decide. (Though I've set
the option and so far, everything works fine.)

Thanks for your help
