* NEWS: Document the cp -p fix for special bits. * src/copy.c (set_owner): Now returns a three-way result, so that the caller can clear the special bits. All callers changed. (copy_reg): Don't set the special bits if chown failed. (copy_internal): Likewise. * tests/cp/special-bits: Test this fix. Signed-off-by: Jim Meyering <jim@meyering.net>
