Description

While testing #3323 I discovered "deal-breaker" was generating several spurious derived forms such as "dedeal-breaker" - it turned out three lines had C++ style comments instead of the correct # comments and the // comments tricked the dictionary+annotation parsing logic to treat it like a separator between the base word and the annotation flags.
