v1.4.0

Three corrections at the root. WORKING.md says, under Identity, that the ruleset rule that would enforce an author address, commit_author_email_pattern, is not available on this plan, tested rather than assumed, and that it would shut out outside contributors if it were. The prose check's stem list gains the forms a sweep of every member found unflagged, generalise, authorise, materialise, penalise, singularise, synthesise and modelled, and the rest of their family spelled out to its endings so that generalist, realism, emphasis, criticism and synthesis stay clear, together with the -our, -re and doubled-l forms that were missing. The conventions spec names the page typography spec as its companion.

A vendored file changed, so every member re-syncs: move the tag in conventions.json and in uses: to v1.4.0 and run sync once. Expect the prose check to name words it did not name before; that is the release working. To take it fresh, from a repository's root:

printf '{ "repo": "robertblust/conventions", "tag": "v1.4.0" }\n' > conventions.json
curl -fsSL https://raw.githubusercontent.com/robertblust/conventions/v1.4.0/conventions/conventions-sync -o /tmp/conventions-sync
sh /tmp/conventions-sync sync
