strace would show the details I'm looking for - but it limits the buffers
by default to 32 characters (there's a command-line option to lengthen it).

to find out who does own things, you can use 'ls', e.g.,

        cd /
        ls -lad .
        cd /homes
        ls -lad .
        cd /homes/purslow
        ls -lad .

> lxstat(2, "/homes/purslow", {st_mode=S_IFLNK|0755, st_size=18, ...}) = 0 

for example (back to strace), I read the display as saying that it's found
a symbolic link whose permissions are 0755.  (but the permissions of the
underlying filesystem are unknown -- permissions of symbolic links don't
matter much, but I got that information for free when my code in Lynx only
is looking to see if there's a link or not).

If I know more about what I'm solving, then I can try to fix it.  Looking
at the code, perhaps this is where more work needs to be done:

             */
            if (S_ISLNK(data.st_mode)) {
                if (!linked) {
                    linked++;
                } else {        /* a link-to-link is a little hard to digest */
                    break;
                    ^^^^^ (might be the problem - worth expanding if so)
                }
            } else if (S_ISDIR(data.st_mode)) {
