[ESS] do not change window configuration under R debugging

[Ramon Diaz-Uriarte]

Dear Alex,

Thanks, but it doesn't solve the issue. And creates a new problem ---for
me--- which is that R does not start in the window where I issue M-x R (if
I change the order, and place display-buffer-same-window first, this new
problem does not appear, but the original issue is still not solved).


Best,

R.
