Refactor shell scripts. - Avoid relative paths, so I can run them from any working directory. - Make a dedicated curl-wrapping shell script instead of re-defining the same alias everywhere. - Support extended offline periods: allow get-webmentions.sh to fall back to the cached copy of my webmentions for up to a day, and don't accidentally destroy it; keep changes atomic. - Verify that the fetched webmentions are legit before replacing the cached ones. - Make shellcheck happy about quoting in vnu.sh by passing the list of files with xargs instead of a shell variable. 2023-11-24 02:45:03 +00:00			`curl_wrapper="$(dirname "$0")/curl-wrapper.sh"`
