Okay, so the bug seems to be in ispell-hunspell-add-multi-dic function. When called interactively, then the following interactive call to (ispell-change-dictionary) has the ru_RU,en_US dictionary as a completion. However, if ispell-hunspell-add-multi-dic was called non-interactively, the completion from the subsequent (ispell-change-dictionary) call seems to be missing.

Not sure though why the difference in behaviour, the "interactive" part of that function look innocent, simply (interactive "sPrompt"). Not sure what starting "s" means though.
