We can't spell it %PP (that would be parsed as "%P" "P"), but we could
take a leaf from %:z (and even %:::z) if we wanted to use : as a flag to
force particular capitalizations.  Of course, even toupper()/tolower()
are locale-dependent, so it's still hard to say what could really be
forced if we added particular variants for overriding a locale's
preferred case.
