That's because of how the T value for evaluation is computed: Spl(I/N,
linear_spline).  No matter how big you make N, the spline will always be
evaluated from I/N to N/N, or in other words, to 1.  If you change the code
to Spl(I/100, linear_spline), and #declare I = -25, #declare N = 125, both
end points show up properly.
