Add a function ft_getpnames_quotes()
It puts quotes " around tokens xxx, when these are enclosed as
V(xxx) and contain arithmetic characters. V(R*C) becomes
V("R*C"). After settig up the parse tree, the quotes are removed again.
Thus these math character remain part of the node name and are not
parsed as parts of an equation.

With <expr1> vs <expr2>, only <expr1> is plotted and <expr2> is ignored.
