Bug description:rename() of dirs accross devices produces confusing copy error

Description:
------------
When a user tries to rename a directory accross filesystems, they are
presented 
with this warning:


PHP Warning:  rename(): The first argument to copy() function cannot be a 
directory in Command line code on line 1
PHP Warning:  rename(t2,/var/run/test/t2): Invalid cross-device link in
Command 
line code on line 1

To contrast this, running 'mv t2 /var/run/test/t2' works without any
problems.


Test script:
---------------
$ sudo mkdir /var/run/test && sudo chown whoami /var/run/test
$ mkdir t2
$ touch t2/a.file
$ php -r "rename('t2','/var/run/test/t2');"


Expected result:
----------------
I would expect the directory to be copied with its contents in their
entirety to 
the new destination, *OR* at the very least, an error message that
specifies that 
one cannot rename directories, as its confusing that it mentions copy
during a 
rename.

Actual result:
--------------
PHP Warning:  rename(): The first argument to copy() function cannot be a 
directory in Command line code on line 1
PHP Warning:  rename(t2,/var/run/test/t2): Invalid cross-device link in
Command 
line code on line 1
