From 28bc3ca8114033a5542e7877105de4f7ec62bf83 Mon Sep 17 00:00:00 2001 From: Edward Welbourne Date: Thu, 15 Oct 2020 17:25:24 +0200 Subject: Fix locale look-up when language is unspecified MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Looking up a locale with unspecified language got the C locale, due to taking a short-cut that would make sense if no locale were found for a specified language. Stop assuming the language was specified.
