Thanks, I did see that, but it didn't immediately bring to my mind 
redirections.  It seemed more a bit of general info for the UA or 
intermediates.  I didn't even get from it a sense that, say, a browser UA 
should update the URL bar with the URI from C-L rather than the requested URL, 
which I would think as a requisite action in any redirection scenario.  It 
does say that the C-L URI should become the base URI of the document, but this 
still seems too weak a stipulation for use in redirections scenarios.

And now, bu mentioning content negotiation, you've caused an even deeper fog 
about my head.  I'm also quite sure how to associate C-L with either content 
negotiation in general (which I think of as getting a gif or png, as 
preferred, from the *same* URL), and redirects from ".../" URIs to 
".../index.html" URLs (which seem more to me as general short-cut support than 
anything to do with clarifying ambiguity or negotiating content).
