The previous logic, whilst not actually wrong, was overly complex and involved doing two binary searches, where only one was really necessary. This simplifies that logic and improves the comments. One visible change is that if the new partition overlaps multiple existing partitions, the error message now always reports the overlap with the first existing partition (the one with the lowest bounds). The old code would sometimes report the clash with the first partition and sometimes with the last one. Original patch idea from Amit Langote, substantially rewritten by me.
