[PATCH] makediffpdf.sh: tool to create marked-up diff

make pdf diff using latexpand and latexdiff-fast  styles are set in diffpreamble.tex: new text is blue, old text is red and is crossed-out.  in diff, links are coloured green instead of blue  Must be run within a git-svn clone of the spec repository.  Note: latexdiff has --flatten option, this and options to select diff style don't seem to work well. So flatten by script myself, and add our own preamble.  Signed-off-by: Michael S. Tsirkin <> ---  The following seems to work OK for me, though it probably can be made prettier. Anyone? Note: I'm using latexdiff-fast tool from cpan: default latexdiff on Fedora does not seem to work well.
