    Warn about dump -recurse nonfunctionality
    
    kdb5_util dump -recurse hasn't behaved as documented since krb5-1.5,
    when the DAL was integrated.  Restoring it is a nontrivial amount of
    work, so just document it for now.
    
    (cherry picked from commit eb8dc865efec4938d74a7955fdcd02bbee4c22b9)
    
    ticket: 8470
    version_fixed: 1.13.7
