Comment (by ylluminarious):

 Just FYI: I've dug a little more into solving this problem, but haven't
 found much. So I posted [https://stackoverflow.com/questions/50575078/how-
 to-append-history-in-editline a question on StackOverflow] about it.
 Hopefully we can get some pointers on what to do here.
