Revert "hygiene, in accordance to valid outputs just print two question marks for unknown intervals"

This reverts commit cadc19d81001138adecf9a0672ecfa9eeca7b258.

The changeset was wrong in the sense that if we have no candle width we certainly won't
have the unit either.  So it's 3 question marks.
