Views generated by each read stat 0, as acme's do: data, xdata, index, layout, recent and listeners; fs.md says which files have real lengths

A stat of index, layout, recent or listeners built the whole view to
count it, and data and xdata reported the body's length though a read
answers what addr selects. Those now stat 0, as screen and pane/new
already did, and fs.md lists the files whose length is real and says to
read the rest to the end.
