[Texmacs-dev] [RFC][PATCH] make kghostview move back through pages

[Igor V. Kovalenko]

Hi!

I'm not an expert in postscript language, so here is a request for comment:
the following patch enables kghostview to page-up/page-down through PS file
exported from TeXmacs. Simply put, this patch replaces nr_pages with cur_page.
