• feat: when the plural form selected for count is missing, t() uses the _other form of the same language before the next fallback language, as CLDR does (lateral inheritance), instead of returning the key. Current CLDR data gives French, Spanish, Italian and Portuguese a many form for exact millions, so files with only _one and _other showed the key (or the fallback language) for count: 1000000. The plain key still comes first, so key + key_other keeps resolving key; with a context, key_<context>_other comes before key_other; ordinals use _ordinal_other; and defaultValue_other is used after defaultValue. A form filled in from _other is no longer reported as missing (saveMissing, missingKeyHandler, exists()). Thanks @TenPotatoes (#2468)
