Discussed in #58

Beyond the work on the translations UI/frontend via Weblate and translating Rd files, it would be nice to close out several issues related to translations in R itself:

Bug ID	Summary	Existing patch?
17819	Translate untranslated char arrays in all library packages	✅
17820	References to R 3.x in translation documentation
17824	tools::update_pkg_po doesn't detect string literals from stopifnot('msg'=test) form	✅
17957	Missing translations of some messages	✅
18025	xgettext/xngettext miss messages when supplied with qualified namespace	✅
18091	tools::xgettext fails on a wrapper of a gettextf
18121	Inconsistency in .pot files for R vs src translations
18131	Add src/unix/sys-std.c to po/POTFILES	✅
18280	Suggestion for base to include templated condition handlers (stopf() etc)
18361	ls.str() not agile to LANGUAGE
18373	custom stopifnot messages should go through gettext() first
18478	Bad pluralization in QC.R for internationalization	✅

Several of them have existing patches that just need to be reviewed/refined, and 18373 is a duplicate.
