Sorry, I failed to accurately represent my argument and opinion on that 
matter there.  I was intending to say that, for example, non-positive 
height floats don't/shouldn't cause line boxes "next to" them to shorten 
or other floats to horizontally abut them (since it's not possible to be 
"next to" them, a fact which is in the process of being codified in 
Issue 185); and also that in the case of non-positive width floats, 
other floats and line boxes do/should abut the margin area edge rather 
than the border area edge - thereby "starting" further left than the 
left margin edge of the float in the case of a left float with extreme 
negative right margin - which is exactly the point I've been making in 
this current thread).  Please ignore my overstatement in the quoted
