_pspacing example

This example uses _pspacing to set the spacing to 1 then 2 lines between lines of text and finally back to 1 line:

_pspacing=1
? "Jack 1"
? "Jill 1"
_pspacing=2
? "Jack 2"
? "Jill 2"
_pspacing=1
? "Jack 1"
? "Jill 1"
// produces:
// Jack 1
// Jill 1
//
// Jack 2
//
// Jill 2
// Jack 1
// Jill 1

Notice that _pspacing takes place immediately so that the double spacing occurs before Jack 2 and before Jill 2.
