Since commit d03001a31a6d460b712825640dba11e3f1a53a14, an object like: (file-append (local-file …) "/foo/bar")
where (local-file …) is lowered to a store item, say, /gnu/store/…-example, would wrongfully expand to: /gnu/store/…-example IOW, the second argument to ‘file-append’ is ignored. Ricardo noticed it in ‘doc/build.scm’, in ‘guix-manual-text-domain’. Ludo’.
