> Is the below better?
> 
>   "Scroll the window so that current line is at the middle of the
> window.
> Successive invocations scroll the window in a cyclical order to put
> the current line at certain places within the window, as determined by
> `recenter-positions'.  By default, the second invocation puts the
> current line at the top-most window line, the third invocation puts it
> on the bottom-most window line, and then the order is reused.
> 
> With numeric prefix ARG, move current line ARG lines below the window
> top.
> With plain `C-u', move current line to window center."
