[GNC] Auto commit with auto save?

[David G. Pickett]

An alternative proposal is to create data elements to allow auto-saving of both the modified and unmodified transaction of uncommitted changes, so if the file is reloaded, the uncommitted state is restored as it was at the time of the save.  Then auto save would ensure these uncommitted transactions are saved as uncommitted, for future discovery after a file load on a *manual* save or graceful interactive exit with save warnings.
