With this option, "cp file symlink" will delete symlink
and create a regular file. This does not conform to POSIX,
but prevents a symlink attack.
Similarly, "cp file device" will not send file's data
to the device. (To do that, use "cat file >device")

If you don't want this, set FEATURE_NON_POSIX_CP to "no"
