cp --recursive --backup broken in 9.2 |

Hi
After upgrading to coreutils 9.2-2 on Arch Linux the following:
mkdir -p src dst
touch {src,dst}/bar
cp --recursive --backup src/* dst
fails with:
cp: cannot create regular file 'dst/foo/bar': File exists
Running strace on cp I noticed:
renameat2(4, "foo/bar", 4, "foo/bar~", 0) = -1 ENOENT (No such file or
directory)
In coreutils 9.1-3 the syscall succeeds:
renameat2(4, "bar", 4, "bar~", 0) = 0
I assume renameat2 is called with the wrong oldpath and newpath in 9.2
and that it should just be the basename and not the full relative path.
Cheers

For completeness the correct repro is:
mkdir -p {src,dst}/foo
touch {src,dst}/foo/bar
cp --recursive --backup src/* dst
The attached two patches should address this.
The first fixes the bug in gnulib (cc'd),
while the second adds a test to coreutils.
Pushed.
Marking this as done.
thanks,
