failed copy_dir call -- otherwise, the failure to read a single file
in a source directory would cause the containing destination directory
not to have owner/perms set properly. Reported by Piotr Kwapulinski.

(copy_internal): Change the || to ^ in the big sameness
test, so copying one symlink onto another, identical one doesn't fail here.
If the symlink call fails, don't report the failure if the destination
already exists and is a symlink pointing to the proper name.

|
(copy_internal): When making backup files in verbose
mode, print the backup file name on the same line as the rest of the
information, e.g., `a -> b (backup: b.~13~)' rather than on a line
by itself.
|
|
(copy_internal): In move mode, if the rename attempt
fails, then unlink any existing destination file. This makes a
cross-device `mv' more consistent with the intra-device behavior.
This change is required by POSIX to make a cross-device move act with
semantics similar to those of the rename syscall. For example now
`mv' can move a file onto a symlink to itself when that symlink
is on a separate partition. With fileutils-4.0j, it would fail with
a diagnostic saying they were the same file.

and *do* allow `mv' to move a file onto a symlink to itself when that
symlink is on a separate partition. With fileutils-4.0j, it would
fail with a diagnostic saying they were the same file.

`mv src symlink-to-src' when src and dest are on different partitions.
Otherwise, that `mv' command would silently remove `src'.

Otherwise, `mv' would not preserve the permissions when copying
between partitions. Reported by David Godfrey

Add a single condition to the existing sameness test.

it follows the `if (new_dst || !S_ISDIR (dst_sb.st_mode))' block.
Prior to this change, `cp --one-file-system' would traverse a file-
system boundary if the destination directory existed.

That is, even though source and destination are `the same,' don't fail

Instead, deduce the move-into-self condition from errno==EINVAL
