Sigh, I haven't finished the lib/deflate.c compression side so it's not enabled
in defconfig, so it doesn't get as much testing. My bad, missed a curve. (It
worked for _a_ file in both directions before I checked it in. I fixed the
"multiple files on the same command line not resetting all the state" on the
decompression side with commit 05444e4ae675, lemme work through the lifetime
rules here and see what I missed on the compression side...)
