/*
 * Construct a description string for a backend to use as
 * backend_description(), or a plug as plug_description().
 *
 * For some backends this will be overridden: e.g. SSH prefers to
 * think in terms of _logical_ host names (i.e. the one associated
 * with the host key) rather than the physical details of where you're
 * connecting to. But this default is good for simpler backends.
