"Move current buffer line to the specified window line.
With no prefix argument, successive calls place point according
to the cycling order defined by `recenter-positions'.
"Scroll the window so that current line is in 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 in a
cyclical manner.
A prefix argument is handled like `recenter':
With numeric prefix ARG, move current line to window-line ARG.
With plain `C-u', move current line to window center."
With numeric prefix ARG, move current line ARG lines below the window top.
With plain \\[universal-argument], move current line to window center."
