History

Get version history for a currency, as a flat table by default. Add --diff for a unified diff instead: unchanged fields as context lines, the server-computed changes as -/+ pairs (or every field as an addition from /dev/null for the oldest version). --version <n> picks a specific version to diff against its predecessor; it is only valid together with --diff. All comparison happens server-side, over the generic history.v1.get subject — the shell performs no comparison of its own.
