The comment is mine, don't trust it. Emacs 22 records undo information
all through the decoding step. That's what I wanted to avoid. But I'm
afraid two insertions get collapsed into one by the undo recording
mechanism and I'm comparing the wrong starting positions. I don't yet
understand how this happens.
