r321: * dh_suidregister: Fixed a rather esoteric bug: If a file had multiple

     hard links, and was suid, suidregister detected all the hard links as
     files that need to be registered. It looped, registering the first
     link, and then removing its suid bit. This messed up the registration
     of the other had links, since their permissions were now changed,
     leading to unpredictable results. The fix is to just not remove suid
     bits until all files have been registered.
