CS, strings and broken plotting



Hello everyone!

At present default gnuplot plotting is broken.
Even simplest plot2d(sin(x),[x,0,3]); complains
about "WITH".  This is certainly due to recent CS
changes and Maxima's specific internal string
representation as symbols. 

Maybe it is good idea to change Maxima's string
representation?   I know that this modification was
not planned for 5.9.2 but suddenly it is turned out to
be tightly entangled with CS.  So maybe now is a
right time to replace Maxima's &WITH by "with"?
