Negative values causing syntax error in robust "has" list

Question

Trying to label robust diagram values as negative numbers causes syntax error:

robust "Debounce" as D

D has 4,3,2,1,0,-1 <-- syntax error
D has 4,3,2,1,0,"-1" <-- also syntax error

@0

D is -1 <-- this works

Comments

Hello D.,

Yes, it seems due to this line of code:

• https://github.com/plantuml/plantuml/blob/6c945e2508936d710789e4d6071ffb6122b953bc/src/net/sourceforge/plantuml/timingdiagram/command/CommandDefineStateShort.java#L63

And here is another funny example: 

robust "D" as D
D has 4,3,2,1,0,1,minus_1,minus_2

@0
D is 2

@1
D is -2

@2
D is minus_2

@PlantUML team: If that can help for debugging...,
Regards,
Th.

Seems that any label containg '-' character causes syntax error when used with "has".
