+Subject: [PATCH] Revert meson plugin translation apply thing
+
+Since meson 0.60, the `build_always_stale` option was removed:
+https://github.com/mesonbuild/meson/commit/6b1a80024c79876dc3b75f2b525be24ca8fe671a
+
+However, meson doesn't make such files depend on the translation .po
+files, which is a known bug:
+https://github.com/mesonbuild/meson/issues/2621
+
+So with that option taken away, I tried passing a list to the input
+which includes all .po files, since I saw it only uses the first element
+for the translations, but that fails when trying to generate po files.
+
+Since it seems you can't dynamically add dependencies after the fact,
+this seems like a dead end, so I am reverting this for now to make it
+compile on meson 0.60.
