Regression: sidebar log messages must preserve tokens that start with `--`.

TerminalController.parseOptions() treats `--*` tokens as options until a `--`
separator. The log command must therefore send options before the message and
use `--` so arbitrary message contents round-trip correctly.

Run with a tagged instance to avoid unix socket conflicts:
