...and Ben's comments notwithstanding...
I'd found the answer through a different channel -- actually didn't answer the question myself. One thing I've found though, over the years, it that I've got a disturbing tendency to turn up my own posts and comments in searching for solutions to problems (probably less a coincidence than thinking through problems the same way, repeatedly, with the concommittant similar phrasing). So if I do find the answer, I'll post it. Because I'll likely stumble on the same question again later.
This is also some of the reasoning going into [link|http://twiki.iwethey.org/|TWikIWeTHey]. I find myself referring to my own documentation not infrequently. I'd like the author to improve the quality and quantity of his output. I'm in a unique position to actually do something about that.... ;-) Seriously, being able to access, update, and get widespread feedback on items helps significantly.
