It undoubtedly is wrong. But it has been wrong forever, or at least
since Tom Lockhart put in the syntax, back in 1997. We've gotten few
complaints --- which means to me that this is not a high-priority bug
fix. I think we should leave it as a to-do item for a future release
cycle, rather than implement some hasty solution for 8.0.
