I'm not familiar with the guts of str[pf]time_l at all, so I cannot
comment on the correctness of your actual code changes here.

I don't think that this decision (whether %OB will return the standalone
case and %B will return the contextual case, or vice versa) should be
allowed to be locale-dependent.  The decision of *which grammatical form
is appropriate* for each context is obviously locale-dependent, but the
rule of which formatter is for which context needs to be consistent
across all locales, so that the _call to strftime_ itself doesn't need
to be locale-dependent.  (Not everyone is going to use %x and %X.)
