It's hard to apply it to output, because you don't know what the
program is going to write out.  At least on input, you can read a big
chunk (buffering does this anyway) and run some tests on the existing
data.

InfoZip has an automatic converter; we should see what heuristics it
uses, since it has a lot more history than we do.
