doc: /* Make display in WINDOW start at position POS in WINDOW's buffer.
WINDOW must be a live window and defaults to the selected one. Return
POS. Optional third arg NOFORCE non-nil inhibits next redisplay from
overriding motion of point in order to display at this exact start.
POS.
Optional third arg NOFORCE non-nil prevents next redisplay from
moving point if displaying the window at POS makes point invisible;
redisplay will then choose the WINDOW's start position by itself in
that case, i.e. it will disregard POS if adhering to it will make
point not visible in the window.
For reliable setting of WINDOW start position, make sure point is
at a position that will be visible when that start is in effect,
