Re: Bug#200542: coreutils: "du /" fails to print "/" on last line

[Jim Meyering]

Thank you for the report!
Here's a patch:

        Fix the bug that would make `du /' omit the `/' on the last line.
        E.g., `du --exclude='[^/]*' -x /' would print only "4\t\n" for me.
        * ftw.c (ftw_dir): Don't clobber the leading `/'.
        Reported by Chris Lesniewski as http://bugs.debian.org/200542.
