The reason why <I> never said anything about it is because it is a documented
restriction, not a bug. For instance, please see:
* Appendix B of the list owner's or site manager's manual, under
"Subject-Tag="
* Chapter 6.1.1 of the site manager's manual, under "SET SUBJecthdr"
* Chapter 5.3.6 of the list owner's manual, under "SET SUBJecthdr"
I will admit that this behaviour does not appear to be documented in the
release notes. However, I would have thought that being documented in
four separate places in the formal documentation would have been sufficient...
