bug#35007: 26.1; Flyspell multi dictionary error

[Philipp Uhl]

Since an update quite recently flyspell (or ispell/hunspell) stopped to
work with my configuration for multiple dictionaries (see below). I
reported a similar bug (Bug#33493) before and it got resolved. It
appears as a similar issue has made this bug reapear.

My complete emacs configuration can be viewed here: 
https://github.com/phuhl/sheeshmacs
My config contains this relevant section:
(with-eval-after-load "ispell"
(setq ispell-program-name "hunspell")
(setq ispell-dictionary "en_US,de_DE")
(ispell-set-spellchecker-params)
(when (> emacs-major-version 24)
(ispell-hunspell-add-multi-dic "en_US,de_DE"))

What update was that?

Does the problem appear immediately after you turn on flyspell-mode,
or does one need to do something to trigger it?  I tried starting
"emacs -Q", evaluating your settings:

> (with-eval-after-load "ispell"
> (setq ispell-program-name "hunspell")
> (setq ispell-dictionary "en_US,de_DE")
> (ispell-set-spellchecker-params)
> (when (> emacs-major-version 24)
> (ispell-hunspell-add-multi-dic "en_US,de_DE"))

Then turning on flyspell-mode, but the problem didn't happen, so I
wonder whether I did everything to reproduce it.  If you do the same,
i.e. start "emacs -Q", then evaluate the above, then turn on
flyspell-mode, do you see the error messages?

Bug#33493 was fixed for Emacs 26.2, which is about to be released.
You are still using Emacs 26.1, where the bug is present.  If this bug
disappeared for you in 26.1, it's possible that you applied the patch
for bug#33493 locally, and now somehow lost that patched version.

In any case, I verified that using multiple dictionaries does wotk in
Emacs 26.2 with Hunspell 1.7.0 (and fails in Emacs 26.1), so this bug
is already fixed, and I'm closing it.

Thanks.
