while we're in a block of code that is executed when the 'dest' is a directory, the "parse" is on "orig" not "dest".  So I think the current code is ok.  Unless I'm not following your point.  Reason I'm asking is because if you think something is wrong, even though its in code I didn't change, I'd be happy to fix it.
