  @var{columns} should be zero or positive; if not, it is taken as zero.
  Fractional values of @var{columns} are not supported at present.
  
+ Note that @code{set-window-hscroll} may appear not to work if you test
+ it by evaluating a call with @kbd{M-:} in a simple way.  What happens
+ is that the function sets the horizontal scroll value and returns, but
+ then redisplay adjusts the horizontal scrolling to make point visible,
+ and this overrides what the function did.  You can observe the
+ function's effect if you call it while point is sufficiently far from
+ the left margin that it will remain visible.
+ 
  The value returned is @var{columns}.
