I was not around at that time, and don't know the history or intent of
the axis.range_is_reverted flag.  =20

Could someone enlighten me on how this is supposed to work?

The current behaviour seems inconsistent, so I am having trouble
trying to make the "refresh" code to behave equivalently.
=46or example, the following pair of commands produce a mirror pair
of plots:
	set yrange [-300:300] noreverse; plot 'silver.dat'
	set yrange [-300:300] reverse;   plot 'silver.dat'

But the following pair produce identical plots:
	set yrange [300:-300] noreverse; plot 'silver.dat'
	set yrange [300:-300] reverse;   plot 'silver.dat'

So I am confused. =20
Does "reverse" mean "interchange the requested min/max"?
Or does it mean "force the min to be greater than the max"?
The latter appears to be true, but in this case the flag seems
very much mis-named.

=46urthermore, some plot/replot/zoom operations appear to
clear this flag;  others do not.  So I cannot count on the
current state of the flag being the same as it was originally.
This again poses a problem for "refresh".

And that's before I even get to splot_map...
