"Pravus" means crooked, faulty, or bad. I'm pretty sure "pravis" is the correct declension to match "gustibus" (a declension "gustus"), but my Latin has unfortunately atrophied substantially from lack of use.

So basically, I changed the proverb from "it is not appropriate to discuss tastes" to "it is not appropriate to discuss bad tastes" --- and left it intentionally vague as to who has bad taste: people who like Git's index, or people who don't.
