How do I check the history size of a binary?  IOW, how to I check the
size of the sum of all the delta-compressions and root blob of a binary?
  That way I can sample different binary types to get a symptomatic idea
of how well they are delta compressing.  I suspect that compiled
binaries will compress well (efficient history) and graphics files may
not compress well (large history).
