Revision 2f3b28f27234a0130583131a6785c44e3dd1cac4 authored by Johannes Schindelin on 09 March 2023, 22:08:47 UTC, committed by Johannes Schindelin on 17 April 2023, 19:15:37 UTC
The `maint-2.30` branch accumulated quite a few fixes over the past two years. Most of those fixes were originally based on newer versions, and while the patches cherry-picked cleanly, we weren't diligent enough to pay attention to the CI builds and the GETTEXT_POISON job regressed. This topic branch fixes that. * js/gettext-poison-fixes t0033: GETTEXT_POISON fix t0003: GETTEXT_POISON fix, part 1 t0003: GETTEXT_POISON fix, conclusion t5619: GETTEXT_POISON fix t5604: GETTEXT_POISON fix, part 1 t5604: GETTEXT_POISON fix, conclusion
