From 1d86877a865338e554aa2480f021da517a86954f Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Fri, 28 Jul 2017 15:18:46 -0400 Subject: [PATCH 4/4] Make --help and --usage translatable. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Patch initially by Miloslav Trmač and revised by Akira Tagoh for popt <= 1.16 which fixes the problem that help messages for --help and --usage seem not translatable. There already was some i18n support for autohelp in popt.c, but not in popthelp.c, where it actually matters. See https://bugzilla.redhat.com/show_bug.cgi?id=734434 for further details, please.
