Sorry, I should have clarified.  I don't think cfile.c needs changing.
It does seem to me that we would have to run separate mkdiffs for each
block that we would delta, which, from what I remembered from the last
time I looked at this code, would involve opening and closing separate
cfiles for each block.  Having said that, I've just scanned the code in
makedeltarpm.c, and I'm not sure why I thought that.

Anyhow, you know this code far better than I do, and I didn't get much
beyond the initial "this is not going to be trivial" assessment (at
least for me).
