redefining labels is a warning now
* Allowing label redefinitions might have been useful when used as comments,
since you will want to be able to define arbitrary comments.
However as flow control constructs, this introduced a certain ambiguity since
gotos might jump to different locations, depending on the progression
of the parser.
* On the other hand, making label redefinition an error might disqualify labels as
comments when writing or porting classic TECO code.
Therefore, it has been made a warning as a compromise.
* Added test case
