Hey, this is marvelous. I have just compiled it and did a few
tests. As one example I included the whole Adobe PDF Reference:

\documentclass[a4paper]{article}
\usepackage{pdfpages}
\begin{document}
\includepdf[pages=1-696]{PDFRef.pdf}
\end{document}


The file size of the pdf file (test-14h.pdf) created with pdftex 0.14h
was out of question. 
The file (test-14hpatch.pdf) created with the Ofrieds patch is even
smaller than the pdf file from Adobe. Seems like Adobe has some
duplicated resources in their files. Now pdftex is first :-)

Another surprise: The running time also decreases a lot with
Otfrieds patch.

# time pdflatex test.tex 

14h:       2m58.318s
14hpatch:  0m19.447s

This is fantastic.
Thank you, Otfried!

Best regards,
Andreas
