(I finally have some time to look at this again.)

I don't think it's worth the extra complexity to handle putting in
ellipses for this case.  I tried a long path with a very narrow browser
window and it wraps sensibly, which I think is acceptable.

Note that the patch here won't display the file at the end of your
second example above - it explicitly checks for directories, which is a
conscious choice so that we don't have to go back and correct the mode
bits in the first column.
