* ext/digest/digest.c (rb_digest_base_alloc,
rb_digest_base_equal): Simplify the equality check and just compare resulted digests since state-level equality should not be significant. * ext/digest/digest.h: Ditto. * ext/digest/*/*.[ch]: Ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@11131 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
