I think the error message has to refer to the ispell dictionary type by
its assigned name, otherwise you'll just create even more confusion.
(In other words, I read the message as talking about PG's ispell
dictionary code, not about somebody else's ispell man file.)

The right place to explain that ispell accepts hunspell-formatted files,
or to link to specifications of what that means, is in the documentation.
Section 12.6.5 already says that, but maybe it could be expanded/rewritten
a little.
