Hello,
looking at the history, it seems that this comment should be updated as in
the following patch (the definition of struct value_range is right below
and explains VR_RANGE and VR_ANTI_RANGE). I am not committing this as
obvious because the text below does *not* actually describe VR_VARYING or
VR_UNDEFINED, and while I know what VR_VARYING means, I am still confused
by VR_UNDEFINED, so cannot write that comment myself.
