An OBJ that was a soft link was resolved and its target object compared,
so two files whose /g/s both point at /z differed when /z did: exit 1,
where h5diff (without --follow-symlinks) compares the links' target paths
and exits 0.
A soft link is now compared as a link wherever it is, OBJ included.
--follow-symlinks compares the objects soft links lead to instead, walks
into soft-linked groups, resolves relative targets against the link's
group, and treats two dangling links as the same; exit codes equal
h5diff's on 14 cases. External links are never followed (documented).
