Indeed:
	1) "first-list-name-printed" [i.e "names" only in that
	   			     context of printing]
	2) Windows GUI version of R only
	   (not 'Rterm', i.e., not in ESS (emacs speaks
	   statistics), nor in Rstudio on Windows

Kevin Ushey has reported this last week in an official (and
perfect) bug report to R's bugzilla bug reporting site:

 https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17447

            Bug ID: 17447
           Summary: list() prints first variable name in backticks
	   ....
         Component: Windows GUI / Window specific
          Reporter: kevinushey ..  gmail ..

His minimal REPREX was even much simpler:

   > list(a = 1, b = 2)
    $`a`
    [1] 1

    $b
    [1] 2


Thank you, Bill, for the nice extra example.
