DfRefactor

I don't understand it as a bug.
Reported by Jose:

Let's assume following code:

Procedure MyProcedure
    String sVarN1, sVarN2

    Move "something" to sVarN1
    Move "test" to sVarN2
End_Procedure

This piece of code is valid for the compiler.
If I make use of unused local variables sVarN1 gets deleted and program doesn't compile.
