Unless, it already exists somehow? It occurs to me that one way to do this is to disallow Emacs from scrolling past the end of a buffer. The default behavior is that with C-l one can scroll past the end of a buffer, so there's empty space displayed on screen. But maybe there's a way to disallow that, so the last line of the buffer is never above the last line of the window. Is there a way to get Emacs to do that? Seems like the kind of thing someone would have implemented at some point.
