cp -pP (and e.g., -a): preserve time stamps on symlinks, too
* src/copy.c (utimensat_if_possible): New function. (copy_internal): Remove variable, "preserve_metadata". Replace with "dest_is_symlink". That covers all cases but one: the one in which cp --link has created hard links to non-directories. In that case, there is no need to update attributes of the links. Use utimensat_if_possible, to preserve timestamps of symlinks. * NEWS (New features): Mention this. * tests/Makefile.am (TESTS): Add cp/preserve-slink-time. * tests/cp/preserve-slink-time: New file. * m4/jm-macros.m4 (coreutils_MACROS): Test for utimensat. Reported in http://bugzilla.redhat.com/230866
