  Modified files:
    usr.bin/tar          bsdtar.h read.c 
  Log:
  A security issue: An archive containing a symlink to another
  directory, then a file with that symlink as a prefix can drop a file
  outside of the current directory, which can be a security hole.
  
  Plug this hole by refusing to extract files if a prefix of the
  pathname is a symlink.  The -P option disables this check.
