There was a single-character miss here, that I only noticed upon
trying to use SSSH from a host to do some diagnostics, as it causes
the `ssh` client to crash complaining about incorrect options.
Conversely, it means these SSH server options were never applied...or
tested, I guess (e.g. inspecting for verbose output that included SSH
key fingerprints, per the comment on `LogLevel VERBOSE`)
