Subject: patch 9.2.0866: MS-Windows: ":language messages" only works once
X-Git-Tag: v9.2.0866^0
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a29d16a3919a12a0e775d50cc67f062c8d7ca33a;p=thirdparty%2Fvim.git

patch 9.2.0866: MS-Windows: ":language messages" only works once

Problem:  On MS-Windows ":language messages" has no effect once messages
          have been translated, the previous language keeps being used.
Solution: Make gettext drop the translations it cached.
