Fiddle with the cmdline_saved mechanism: the `-load' option is now

Fiddle with the cmdline_saved mechanism: the `-load' option is now
never deferred, but is evaluated instantly. This _should_ fix all
the irritating problems with (for example) proxy settings and saved
sessions not playing nicely. Or it may have some other ghastly side-
effect I haven't considered; really I ought to have been keeping
better track of all the problems in this area :-(
