Documentation

Set WINDOW's buffer to BUFFER.

WINDOW must be a live window and defaults to the selected one. Optional argument START non-nil means set WINDOW's start position to START. Optional argument POINT non-nil means set WINDOW's point to POINT. If WINDOW is selected this also sets BUFFER's point to POINT. If WINDOW is selected and the buffer it showed before was current this also makes BUFFER the current buffer.
