redundant code in kalman #1516
Description
The lines
current_wpt->wpt_flags.marked_for_deletion = true;
extra_data->is_zinger_deletion = true; // Mark as zinger deletion
always appear together.
If we assume that waypoints aren't marked for deletion on entry then is_zinger_deletion seems redundant with marked_for_deletion.
It seems the original intent was to allow for "This is a marked point but NOT a zinger", but I don't see that this can ever occur.
