<U+1820, FVS3> must be treated the same as U+1820, for the variation
sequence is not defined.  Once <U+1820, FVS2> ceases to be specified
for any position, then the same will apply to <U+1820, FVS2>.

It is not clear what should happen if only some positional variants are
defined for a variation sequence.
