I didn't just read the man page, I also looked into several *.aff
files that install with Hunspell dictionaries.  It is clear to me that
WORDCHARS is at least unreliable, even if your interpretation is
correct (of which I'm still unconvinced): some *.aff files don't have
that entry at all (e.g., en_GB.aff, whose OTHERCHARS should include
the ' character, and also ru_RU.aff); others, like he_IL.aff, have
that entry mention all the CASECHARS, in addition to OTHERCHARS.  I
wouldn't bet my money on what that entry gives us.

Good news, indeed!  Thanks!
