Bug: Try to copy folder "dir1" into folder "dir2" containing regular
---  file named "dir1".
     1. mc will not report any error.
     2. You will see that "dir1" file attributes were rewritten with
        attributes of folder "dir1".
     3. Moreover if you will try to move the folder instead of copy,
        it will be lost without any warning...


...Bye..Dmitry.
