There is a serious flaw in the CR case! You lose orthogonality in
the interpretation of commands since creations, moves, copies and
some other file operations will interpret arguments literally while
other commands will have their arguments interpreted in the flexible way.
A move by the way is a good example since one argument will be treated
in one way and the other in the other way.
