    Revert "enmasse: For the special case of 2 args, do not distinguish between 
dirs and files"
    
    This reverts commit a564a67c4ea70e90a4dc543814458e4903869d3e.
    
    Not as trivial as I thought.  This breaks cp when used as:
    cp -r /foo/bar /baz
    
    The old code expands this to:
    cp -r /foo/bar /baz/bar
