Fix redisplay when scrolling under redisplay-dont-pause

Browse source 
* src/dispnew.c (update_window): Reset the window's
'must_be_updated_p' flag if the window's update was completed
without interruption.  This fixes redisplay glitches when
'redisplay-dont-pause' is nil, at least on MS-Windows, because
'expose_window' doesn't redraw the exposed rectangle when the
window's 'must_be_updated_p' flag is set.
