Please let know if you notice anything wrong. For debugging purposes, I found it easier to have the attached patch applied, so that replacements are easily distinguishable from the original packages. You might want to use it too. :-) (I didn’t apply it to master because it would lead to merge conflicts in core-updates, but feel free to apply it if that seems OK to you.) Thanks, Ludo’.
