save-load-export: clear cli-parsing default

...in order to silence Cobra's usually-helpful "(default xxx)"
message.

Initialization is now done in code, by testing for empty string
and setting that to /dev/std{in,out} as appropriate; make special
note of load.go where there's mild duplication between a local
variable and cliconfig.
