md5sum now accepts the new option, --quiet, to suppress the printing of
'OK' messages. sha1sum, sha224sum, sha384sum, and sha512sum accept it, too.
+** Improvements

+ Improved support for access control lists (ACLs): On MacOS X, Solaris 7..10,
+ HP-UX 11, Tru64, AIX, IRIX 6.5, and Cygwin, "ls -l" now displays the presence
+ of an ACL on a file via a '+' sign after the mode, and "cp -p" copies ACLs.
