It's not quite possible to just import the default from the saved for two
reasons:
1. I don't know of any way to import the default.  It's not stored at any
well-known address or with any well-known size.
2. The order of precedence would be a little different (default would
override saved).

...but I think you're right that using "env import" is the better way to
go.  I can always have the default boot command load the "overrides" into
memory and the import them.  That works just fine for us.

Thank you for your review and suggestion!

Please consider this patch abandoned.
