I can't believe we don't have a ticket for this yet!

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 worthwhile: http://docs.lib.purdue.edu/cgi/viewcontent.cgi?article=1377&context=cstech thread: http://thread.gmane.org/gmane.comp.version-control.darcs.user/26797/focus=26800
