nnn: [Bug] Invisible Icon Files on Mac Not Displayed

In folders for which a custom icon is set, the Icon\r / Icon? / Icon^M^M file within is not properly displayed. It is accounted for in the total at the bottom but it looks like a blank entry in the list, both with dotfile display on or off. Moving the cursor down one entry: The entry is invisible both on Mavericks and on latest Sierra.
