So we should certainly drop the 'lvchange:' now from the second line of output.

So should we add a new option (command_names = 2, perhaps)
that only applies it to messages produced using log_error()
rather than for all output?  [And make this the default setting.]

Or do we only want it (roughly speaking) for EINVALID_CMD_LINE not for
ECMD_FAILED?
