Ok, regarding the grammar build, learnt that this commit changed things: https://github.com/helix-editor/helix/commit/b157c5a8a4472cff68de3a9be66e220dc4b80a9f So if I do a `MAKE_ENV+= HELIX_DISABLE_AUTO_GRAMMAR_BUILD=true` then we can carry on fetching grammars as we were. Will try to take a proper look through the patches and then propose a proper update to get us to 23.05; 23.10 is now out so we are currently two versions behind.
