For anyone who follows this stuff from the mailing list messages, rather than viewing the issues web page, note that I made 3 small edits to note 4070 as it was sent to the list (all inconsequentially really, but...)
Two of them were to fix the range of line numbers in the third last line of the note, where I say what the subsequent note is going to do (that note (4071) had them correct, but I had a brain fade when ending this note (4070), got both ends of the range wrong, and then took 2 edits to fix it...) The other was to add the blantantly ovbious mention of "value of R" in the paragraph that summarises the actions of word expansion in redirects iin the various shells. kre
