Suppress -0 in the C field of lines computed by line_construct_pts().
It's not entirely clear why some PPC machines are generating -0 here, since
the underlying computation should be exactly 0 - 0. Perhaps there's some
wider-than-nominal-precision calculations happening? Anyway, the best way
to avoid platform-dependent results seems to be to explicitly reset -0 to
regular zero.
