Thanks for the bug report. How about the attached patch instead? It's a bit more conservative than what you proposed. (I haven't tested it.)

After testing it I see that patch wasn't right and that the patch you proposed was better. However, I now see another bug in this area. So I installed the attached three patches. The first two add a test case and fix for the other bug; the third one is very close to your patch so I'm giving you author credit (it's small enough to not require copyright paperwork).

Thanks again for reporting this.
