Oh, one other thing to point out...  Since we're setting the
labels' strings once, at launch, this means the Japanese
(and any other locales affected by this) will NOT automatically
respond to changes in the window size, like they do for other
locales.

Of course, this was already the case, so it's not a regression.
It's just something we COULD handle ourselves, but do not at
this time.

In the end, because the app was not originally written to be
"responsive", we're having to deal with a lot of this junk
ourselves.  I should buy a book on Qt or GTK+ and rewrite
this poor old thing.  (It just had it's 19th birthday
a couple days ago! :^D )
