Some users have experienced a few false positive clojure.core/format warnings with the new clj-kondo. I have a fix for this on master. Could anyone who ran into this check if this is fixed with:

$ clojure -Sdeps '{:deps {clj-kondo/clj-kondo {:git/url "" :sha "91b6c55f5290fcfa9032ab221a6fc1b79af18827"}}}' -m clj-kondo.main --lint src test

Pushed out a new version: https://github.com/borkdude/clj-kondo/releases/tag/v2020.07.29
