Subject: [bug#40367] [PATCH v2] lint: Display result of checkers on stdout.
Date: Wed,  1 Apr 2020 15:19:25 +0200

* guix/scripts/lint.scm (emit-warnings): Use 'current-output-port'
instead of 'current-error-port'.
---

This version is rebased on top of master and only change the output port to
stdout for the result of the checkers, not for the progress or any run-time
errors.
