I've added a customization variable to ob-gnuplot which may be used to
map file extensions to terminals.  Currently it just holds the mapping
from eps to "postscript eps"

    ;; -*- emacs-lisp -*-
    (defcustom *org-babel-gnuplot-terms*
      '((eps . "postscript eps"))
      "List of file extensions and the associated gnuplot terminal."
      :group 'org-babel
      :type '(repeat (cons (symbol :tag "File extension")
                           (string :tag "Gnuplot terminal"))))

If anyone knows of other good default mapping to add please let me know.

  WRT |, I've also added the *org-babel-gnuplot-prefix* variable, which
may be set to e.g., "reset" to reset the gnuplot process between code
blocks.

Thanks for the feedback.
