gnuplot.texi missing postscript terminal docs

[Hans-Bernhard B. <br...@ph...>]

Ethan, (or whoever feels up to it), 

please fix the doc sections of term/post.trm such that they make it into
docs/gnuplot.texi (and other files built from it).  It looks like the
driver tries to be too clever, relying on C preprocessing tricks to
generate repeated text blocks, which doc2texi.el can't follow.
