Summary:                    mv silently returns success when trying to mv a file
to itself (mismatch with coreutils)
Description: 
when trying to mv a file to itself, coreutils gives a warning and returns
an error, but busybox silently returns success.  I've reproduced this in
the latest svn head as of today.

Coreutils behavior:

$ echo 'hello' > A; mv A A
mv: `A' and `A' are the same file
$ echo $?
1

(exit code of 1 signifies error)

Busybox behavior:

$ echo 'hello' > A; ./busybox mv A A
$ echo $?
0

(exit code of 0 signifies success, and no warning message printed)
