So it's a problem on the hunspell side, and not because Emacs is
considering the "." to be a non-word character?  (I haven't tried to
debug what's going on.)

There's also a problem in common abbreviations like "i.e.", which is
considered as the words "i" and "e", apparently...

I was wondering whether Emacs could query the backend speller whether it
had the word "foo." in the dictionary before squiggly-lining "foo", but
I'm very unfamiliar with how these functions work.
