Hello,

Here is a minimum example of the bug:

  #mkdir testcp

  #cd testcp

  #mkdir origin

  #touch origin/a

  #cp -r origin destination

  #cp -r origin destination

The expected result is:

#tree

├── destination

│   ├── a

└── origin

    └── a

or even this, who would I be to judge:

#tree

├── destination

│   └── origin

│       └── a

└── origin

    └── a


But this is unacceptable:

#tree

├── destination

│   ├── a

│   └── origin

│       └── a

└── origin

    └── a

The result is worse if you add a file in between copies. Now you would have 3 a files and 2 b files.

Thank you,
Tomás
