tobez 33bcab2805 Adds sha256 support. While it is a good idea to also add sha384 and
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.
