Details:

This patch corrects 2 problems:
1. print -Pa_printer introduces an extraneous -P so that
   the resulting lpr command fails. Removed -P.

2. The test for the presence of a figure at the beginning of
   print() fails to detect the lack of a figure. This may
   be due to a change in isfigure(). If there is no figure
   and the opts.figure value is set to empty, isfigure returns
   true. Use of isempty instead of isfigure fixes this.

In addition I edited the print help info. Currently it was
unclear and referred to the ability to generate TeX (as
opposed to LaTeX.  Since it unconditionally gereates LaTeX
I removed the TeX references and tried to clarify the operation
of the latex modes.

The print command is quite complex and handles lots of different
cases and both fltk and gnuplot. So, it would be helpful if
these patches could be tested in other environments.  So far
they work for me and make generating plots with real TeX in the
text strings much more convenient.
