I think this window-splitting is because TeX-recenter-output-buffer
(bound to `C-c C-l') calls `(TeX-pop-to-buffer buffer t t)', which calls
pop-to-buffer with the ACTION argument set to t, which according to
pop-to-buffer's doc string " means to pop to a window other than the
selected one even if the buffer is already displayed in the selected
window".  Maybe AUCTeX should have a user option that can be passed as
the ACTION argument to pop-to-buffer.
