It seems to need a variable or function ... e.g.
is_wxt_windows_active()?

I see this on Linux:
set term wxt
plot x
<close the window>
pause mouse any
<need to press Ctrl-C>

The same for "set term x11".
On "set term windows": <need to press Enter>

I think it would be better to require <Enter> on all platforms if wxt or x11 
window is not available.
