Fixed. All three properties seem to be satisfied in GHCi now. Beware of
prop_DecEnc, though, quickCheck erroneously claims to falsify it. I
guess this is caused by a bug in GHC 5.04's handling of strings that hit
the list some time ago (try "\666"=3D=3D['\666']). Manually applying
prop_DecEnc to the alleged counter example has always yielded True for
me.
