Previously, using a non escaped Relational symbol within a _Format_ segment would throw an IAE.

This is safe to do, as any subsequent relational symbols should only come after a '|' is parsed, which sets part back to 0. This ensures that for the duration of `part = 1` (Format segment), the relational symbols can be used without syntactic meaning.
