That is fairly easy to address in drawnow:enhanced_term.. We just have
to check if the terminal is (e)pslatex, and don't flag this as an
enhanced terminal. I can't easily regenerate a new patch, for this patch
at this point, but will make this change if you accept this patch..

No that isn't intentional.. I'll fix it before committing if you accept
the patch.
