Sorry for the late reply.
This is a problem in the textformatter. I think it'd be great to have
that actually support both holes and dupes in explicitly numbered
parameters. That said, it's not the best-owned code, so if someone
volunteered to file and fix that bug, that'd be great.
That said, once that'd be fixed, it raises the question on how to make
compare-locales understand that some stuff works on central but not on
beta yet. IIIInteresting.
