I think you can replace the entire #ifdef clause at command.c(rlgets) lines 2718-2751
with the single line
	add_history(line);

This works for all three cases of the #ifdef.
Note that the built-in readline already acts this way.

An intermediate option would be to suppress only duplication of the
previous command.  This is what the comments say the libedit version
does, but the code seems to contradict that (I have not tried it).
I think you could get that behavior by replacing
	found = history_search(line, -1);
with
	found = 0;
but again I have not tested.
