Bug : SpurGear Script + Undo

 From:  PaQ
Hello Michael,

It's propably something wrong in the script itself, so I don't expect any suppot from that.
Anyway here are the steps :

- Create one or two object primitives
- Execute the SpurGear script
- Click to choose the center point
- Before changing any settings, just hit undo
- The undo go one stop to much in the history and remove the last primitive created too.
