    cp: Rename -d option to -P
    
    The -d option is a GNU extension and is equivalent to its "-P
    --preserve=links" options.
    
    Since we don't implement the --preserve=links functionality anyway (it
    means preserve hard links between files), just call it -P, which is
    specified by POSIX.
    
    Additionally, there is no need to check for cp_Pflag again before
    copying the symlink itself because the only way the mode in the stat
    will indicate a symlink is if we used lstat (which we only do if -P is
    specified).
