And --verbose + -l would list the dictionary files with their full path:
$ voikkospell -l --verbose
smn-x-standard (/path/to/dict.file): Giellatekno/Divvun/UiT fst-based speller for Inari Sami
or something like that.
This way it is possible both to always get a full list of directories searched, and it will also help developers/linguists in cases of dictionary conflicts (several dictionaries for the same language - a surprisingly common error source:)
