Whoops, I totally missed that there was already a separate thread on the 
libstdc++ mailing list only.  My bad.  :-(

I came up with the attached patch for the wording change.  I'm having 
trouble regenerating the HTML version of the manual, though; it looks

"right" version is.  :-S  Any suggestions?
