Rye.shell does not setup the cmd field of the RAP out object

[rrepen]

The RYE::SHELL has this code:
...
rap = Rye::Rap.new(self)
rap.add_stdout(stdout || '')
rap.add_stderr(stderr || '')
rap.add_exit_status($?)
rap
...

To get the cmd string back I have added the following two lines
...
cmd = Rye.prepare_command(cmd, args)
cmd_str = cmd.dup # Take a copy of the command before it gets the redirection part
cmd << " 2>#{tf.path}" # Redirect STDERR to file. Works in DOS too.
...
rap = Rye::Rap.new(self)
rap.add_stdout(stdout || '')
rap.add_stderr(stderr || '')
rap.add_exit_status($?)
rap.cmd = cmd_str # Add the cmd string to the RAP object
rap

By doing this I get back the command string and I have the same behavior as using a the Rye::Box
