It was your Bug#53771. We didn't come to a nice solution in that report, so your memory is fine in that regard. The problem was that you are working with a non-font-lock-mode buffer, so highlighting is not automatically updated. OTOH, repeating highlight-regexp with the same pattern does nothing. So I think you must first remove the pattern (unhighlight) and then add it again. You can try to do this automatically. Michael.
