I think you may want both. Keep in mind that your existing behavior is
exactly correct for those who create their entries by passing a null to
gnome_entry_new. You could try special casing the empty string case, but
personally I'm a big fan of the "a null is not the same as an empty
string" theory.

Yeah, I'll crack away at this to see if I can get something that I like.
Thanks again for the documentation pointer.

Yeah, it does work, indeed, you don't have to ever invoke
set_history_id(). If you never set it, then your "history" is never
persisted. If you set_history_id() after creation, it doesn't appear to
load the history, but will persist it. Bizarre but true.
