No... we use the vdelta algorithm to produce block-copy instructions,
and we use a home-grown "svndiff" format for encoding those
instructions. vcdiff would be more compact, but probably only a little
bit, and we found that it was much more complicated than we were
comfortable with.

Well, you can search for "vdelta" or "vcdiff" in the mailing list
archives, or browse them starting around August 2000 (maybe a little
before that).
