That's what gretl (gretl.sourceforge.net) does, when calling
gnuplot (well, minus the last bit, using gs).

I would support making pdfcairo the default pdf terminal (which I
think Ethan suggested).  That is, if you have both cairo and
pdflib support in gnuplot, then

set term pdf

would do the same as "set term pdfcairo", and you'd have to do,
e.g., "set term pdflib" if you wanted pdflib to be used.  (But of
course if pdflib is supported but cairo is not, then "set term
pdf" would be equivalent to "set term pdflib".)
