I don't think it's worth the effort. The old no longer existent options 
stored in the options files are harmless and simply unused by the ports 
Makefile. The options files are not intended to be user editable / 
viewable. The old options will be removed when some changes will be saved.

And I am not sure that this is a problem of poudriere. I think it's 
rather issue in ports options framework. Isn't it?
