prelude-moddules.el isn't copied to the installation directory

prelude-moddules.el isn't copied to the installation directory and the reason is this: 

 [ -n "$PRELUDE_INTO" ] && cp "$PRELUDE_INSTALL_DIR/sample/prelude-modules.el" "$PRELUDE_INSTALL_DIR"

Handling the case where the -i argument is given is already done in line 199, putting it again when copying prelude-modules will cause this error as [ -n "$PRELUDE_INTO" ] will only evaluate to true if the -i argument is passed to the script.
