I guess the idea was to use "persist" when gnuplot exits _itself_, i.e.=20
when the input is a script and gnuplot reaches the end.

That's how it works for the x11 terminal.
But as wxt (and the windows terminal too) lives _in_ gnuplot, this=20
meaning doesn't make sense anymore, and becomes :
"Don't exit until all plot windows are closed."
And then, why not supporting mouse operations since we can ?

I also have a couple of plans for post-4.2 regarding mouse interaction,=20
now that I am a bit more familiar with the current behaviour.
The svg stuff seems very exciting by the way.
