Adjust guidelines for %autorelease+%autochangelog
    
    See https://fedoraproject.org/wiki/Changes/Rpmautospec_by_Default
    
    The general approach is the the previous recommendations are described
    with "may" and moved to the end or to a separate page. Use of
    rpmautospec is shown briefly, but with enough information for normal
    packaging workflows. Links are provided to the rpmautospec docs in
    case packagers need more information.
