Please elaborate; what precisely is this ticket about?

At present, darcs does not have any representation for the differences between
binary files.  Surely there must be some better approach than storing both the
old and new version in each patch?

See also http://bugs.darcs.net/issue1009 , I think.

One way we could do is use one of the special-purpose binary diff tools
like xdelta (http://xdelta.org/) or bsdiff
(http://www.daemonology.net/bsdiff/). They're both generally aimed at
patching executables, but I figure they're still better than copying on
each revision.

I'm not sure that I understand how these may all work together, but
someone on the mailing list said that block-move diffs are perhaps more
