- * Some command-line parameters need to be saved up until after
- * we've loaded the saved session which will form the basis of our
- * eventual running configuration. For this we use the macro
- * SAVEABLE, which notices if the `need_save' parameter is set and
- * saves the parameter and value on a list.
- *
- * We also assign priorities to saved parameters, just to slightly
- * ameliorate silly ordering problems. For example, if you specify
- * a saved session to load, it will be loaded _before_ all your
- * local modifications such as -L are evaluated; and if you specify
- * a protocol and a port, the protocol is set up first so that the
- * port can override its choice of port number.
- *
- * (In fact -load is not saved at all, since in at least Plink the
- * processing of further command-line options depends on whether or
- * not the loaded session contained a hostname. So it must be
- * executed immediately.)
