-------------------------------------
New tests failed due to non-deterministic behavior of directory listing order
across operating systems.

> The command only works if its argument is a directory
> If the argement is a file or a wildcard, it does nothing without any message.
> If not arguments are given, the command fails with a stack dump.
> The improved version should:
> -- produce an error message in case it cannot perform meaningful action (no
> argument, or no matching files)
> -- copy the files specified by a wildcard expresstion. (A single file is
> special case of this).
