CLI: "change parameter type" doesn't work

[willkill07]

> list class A
A
        int x
        void draw (g Graphics)
> change parameter type A draw g Graphics Graphics
Class type does not exist
> change parameter type A draw g Graphics Graphics

Please be consistent. Please test.

Works now

> listcls
A
	x int
	void draw (g Graphics)
> cpt A draw g Graphics Graphics
Successfully changed parameter Graphics's data type to Graphics of method draw of class A
> listcls
A
	x int
	void draw (Graphics Graphics)```
