A look at a ./ or ../ name that is not there names the file, not the pane's directory

Any relative name that opened nothing was blamed on the pane's directory (look: .../work/many: no such directory) though it exists; the directory is named only when it is gone. A plain name is still looked for as text, its miss logged as any look's.
