update prints Fossil's receipt on stderr (per-file UPDATE/ADD/REMOVE/MERGE/ CONFLICT, the from/to block, the undo hint) and gains -n, --latest and -v. Every sync-family line names the peer, a no-op is always 'already in sync', clone prints the project code, an unreachable peer is named, and pull/push/ sync show per-round progress on a terminal. commit takes -M FILE, composes the comment in $VISUAL/$EDITOR/--editor over a template of the change set (kept in .zit-ci-comment when the commit then fails), and gains -n and --allow-empty; --no-warnings is accepted as Fossil's spelling of --no-checks — the content gate stays opt-in by design. The names current/ ckout, prev/previous and next resolve against the checkout. The muscle harness now enforces all of it. Closes zit#157, zit#158, zit#159, zit#160, zit#161. check-in: e5beabd7c0 user: dmestas tags: trunk
