@ -1490,6 +1490,8 @@ This function sets @var{window}'s vertical scroll position to
@var{lines}. The argument @var{lines} should be zero or positive; if
not, it is taken as zero.
If @var{window} is @code{nil}, the selected window is used.
The actual vertical scroll position must always correspond
to an integral number of pixels, so the value you specify
is rounded accordingly.
