Using end for indexing cells does not work here:

$ octave-config --version
2.1.63
$ octave -q
octave:1> a={1,2,3};
octave:2> a{end}
error: invalid use of end
error: evaluating argument list element number 1

If this did work in 2.1.57, then its failing in 2.1.63 is probably
unintended.  I am Cc:ing this message to octave-maintainers.

The xwin driver of PLplot uses its own Hershey fonts, which are generated by
regular plline commands.  No X11 fonts are used.
