Another observation, every time a new package is saved, SqueakSource
produces a .mcd diff with its ancestor.

Except, if there are no other versions of that package (e.g., the
first one being copied in), it produces a .mcd as if against an
"empty" package, so the .mcd is as large as the .mcz because it has
everything.
