bug#29788: chown: recursive operation with "-H" flag does not work as documented

[Michael Orlitzky]

The documentation for the "-H" flag to chown says,

  The  following  options modify how a hierarchy is traversed when the
  -R option is also specified.  If more than one  is  specified,  only
  the final one takes effect.

    -H     if a command line argument is a symbolic link to a directory,
           traverse it

This is not doing what I think it should do. In a terminal, as my "mjo"
system user, I can run,

  $ mkdir foo
  $ mkdir bar
  $ ln -s ../bar foo/baz
  $ sudo chown --verbose --recursive -H root foo

which outputs...

  changed ownership of 'foo/baz' from mjo to root
  changed ownership of 'foo' from mjo to root

However, the path "foo/baz" was not passed on the command-line, and
chown did in fact follow the symlink,

  $ ls -l | grep bar
  drwxr-xr-x  2 root mjo 4.0K 2017-12-20 13:19 bar

as evidenced by the fact that "bar" was created as mjo:mjo.
