Subject: Fileutils.cp bug?

I'm experiencing the following behavior in the latest CVS copy of ruby on 
both Windows and Linux.  I think it's a bug.

[chad@ns1 chad]$ cat test
Goodbye Cruel World!
[chad@ns1 chad]$ ruby -rfileutils -e 'FileUtils.cp("test", "test")'

[chad@ns1 chad]$ cat test
[chad@ns1 chad]$ ls -l test
-rw-rw-r--    1 chad     chad            0 Nov 17 08:35 test
[chad@ns1 chad]$


I would suggest the following small change.

Do others agree that this is a bug?

Thanks,
Chad
