Description:
        Bash completion doesn't work properly with AFS.  This could be
        solved easily by configuring with --with-afs, but Matthias
        wouldn't do this for debian, because:

          /* We have to use access(2) to determine access because AFS does not
             support Unix file system semantics.  This may produce wrong
             answers for non-AFS files when ruid != euid.  I hate AFS. */

        So it appears as if bash has to distinguish between files on
        afs mount and others for decent non-buggy bash completion,
        something along these lines:

        read(/proc/mounts);
        ...
        if (file_is_on_afs(path))
                eaccess(path, mode);
        else
                access(path, mode);

        Getting this right does mean a bit of work, so I'll politely
        step back a bit and see if anyone else likes to do it. ;)
