Actually, the value returned by dired-current-directory is always an
empty string of default-directory is the same one as the directory
where the file on the current line lives.  IOW, the issue is not
limited to "/" as the current directory of the Dired buffer.

I think this is just something that needs to be clarified in the doc
string, so I just pushed such a change, and I'm marking this bug done.

Thanks for looking into it.
