* src/copy.c (copy_reg): Suppress SELinux ENOTSUP warnings consistently between the destination being present or not. Previously we did not suppress ENOTSUP messages when the destination was present. (copy_internal): Use the same ENOTSUP supression method as copy_reg() even though the issue was not seen in this case. * tests/cp/cp-a-selinux: Add a test case for the issue and group the other test cases in the file more coherently. * tests/cp/cp-mv-enotsup-xattr: Do the same check for xattr warnings, even though they did not have the issue.
