Uh, my plan was to just change makedeltarpm.c and delta.c, what
do you want to change in cfile.c?
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).
