And because that's bad,  wgnuplot prints this message in such case,=20
right on the startup screen:

There's not much that could usefully be done about that --- there's no=20
single replacement that would be equally applicable for all Windows=20
platforms.

Now that we have the code to locate a suitable fall-back location (for=20
wgnuplot.ini), arguably all other state save files should go there, too
(i.e. gnuplot.ini, the cross-session history file, and whatever else).

That's pretty much guaranteed to be wrong (not to mention isn't even=20
accessible to normal users on a properly installed, modern Windows).
