A .gitignore or .dockerignore lacking the canonical last line no longer
stops the script: each line the canonical file has never held goes
below the fetched content. An .editorconfig lacking it is replaced,
unless it has such a line, which stops the script.
The stub curl now writes files with no execute bit, as a real download
does, so the tests exercise the mode the script sets.
Model: opus-5-5
