Re: set autoscale fix; set logscale y2

IMHO gnuplot reacts as it should:

everything looks right, the y*ranges are defined,
so it doesn't matter that the y2axis isn't used.

here, the defined y*ranges are forgotten, yrange is
calculated from the function values and then - because
y2tics is set - copied to the (not used!) y2axis,
where, in order to prevent errors (logscale y2 !), the 1 to
100 yrange is converted into the 1e1 to 1e100 y2range.
(if yrange would be [0:100] it wouldn't be possible to
convert it into a log-range for y2axis, i think that's the
idea behind this conversion)

keep in mind, that y2axis is plotted but not used.

using both yaxes

plot 1+x*x, 1+x*x axes x1y2

solves the problem.
