 Nothing from a functional point of view - however, this is not how the
 4-STABLE passwd command behaved.  I believe that other programs (like
 Samba) that are dependent upon core system utilities will break.  This
 will be a major source of frustration for many admins.  Perhaps I should
 have filed this PR under 'advocacy'?

 Apologies - my mistake.  This is the incorrect output for 4-STABLE.
