I bind it to `C-l' in place of `recenter'. If there is interest, then perhaps `recenter' itself could have this behavior (but the frame redisplay behavior might need to be taken into account). With a prefix arg, it's the same as `recenter'. Otherwise, it alternately moves the current line to the center, top, and bottom of the window. In this, it's a bit like `C-M-l'. It's a trivial change, but I find it useful - I have no need for repeated `C-l' to keep doing the same thing.
