Log:
  Fix mergemaster -U by forcing FreeBSD 9 compatiblity in mtree when mtree is
  nmtree.
  
  The mtree output used by mergemaster in this case was clearly not meant for
  computer consumption and an approach based on -f <file1> -f <file2> would
  probalby be a better idea, but this is a minimal change.
