the current glibc policy is the one I outlined in my two 2008 posts -
day array should always begin on Sunday and week specifier set in
accordance with that, to preserve best backwards compatibility with
applications expecting this. Then, first_weekday field should indicate
the actual first day of week in the locale.
If you see any particular locales not matching this practice, can you
please point them out? Maybe we missed out some when sanitizing this.
Certainly no locales should currently now be "being moved to day/abday
field _not_ starting on Sunday."
