I would try making the nilValue "%SP;-%SP; -". That is two separate possibilities for nilValue, one is space-hyphen-space, the other just hyphen. (It's a whitespace-separated list of nil values tokens.)
The first one will be used for unparsing. Both will be tried for parsing. That along with justification left might work.
