I just opened all the .po files in poedit, not just those recently updated.
Some of the .po files (Macedonian for one) don't even define Plural-Forms.
Among those that do, the only other ones for which poedit warns about
unusual plural forms are:
Bosnian, Croation, Slovenian, Polish, Russian.
No warnings for these other Slavic languages that do define it:
Belarussian, Czech, Slovak, Serbian (Latin), Serbian (Cyrillic).
A close look shows that those that warn do what Yuri did for Ukrainian,
using four forms, which he convinced me is really better, but those that do
not warn use only three forms, and perhaps they should be changed if we get
more updates. Pavel Fric gave a Czech update only last November.
There is also Bulgarian, with no warnings, but I understand that one
doesn't decline nouns and has simpler number rules.
