These patches to the xpdf 0.80 package improve its pdftotext utility, to
make it better for indexing PDF files.  (The pdftotext program is used by
parse_doc.pl.)

xpdf-0.80-deltax.patch   - This patch fixes handling of PDFs that use large
                           character spacing to separate words.

xpdf-0.80-rawdump.patch  - This patch adds a -raw option to pdftotext,
                           so it can index multi-column PDFs without having
                           the text lines from all columns run into each other.
                           It assumes that the program that generated the PDF
                           outputed all the text in the right order.

The patches are made obsolete by the recent release of xpdf 0.90, which
includes these fixes with improvements.
