I can't think of any at the moment.  I've avoided doing this in the
past because I didn't think parsing the output from gnuplot would be
reliable.  Will the output change from version to version?

Should the output that doesn't match what we are looking for be
displayed or discarded?  Error messages from gnuplot go to stderr,
correct?  If so, then at least those won't be lost.

If it works, then why not use popen2 unconditionally?
