sha512, I did not do that since it is not entirely clear where "the one true place" to hold their implementations is going to be. Sha256 is different since mtree already links against libmd. Make recommended procedure for integrity checking in the manpage consistent. Fix a bug with -f spec1 -f spec2 comparison, which prevented test/tes03.sh from running successfully.
