    doc: clarify the format of placeholders
    
    Following the patch "Doc placeholders", there was a question about
    adding a formal rule on writing placeholders in description paragraphs.
    
    One agreed output was that the placeholders in paragraph must be
    surrounded by angle brackets and not set in literal with backticks.
    
    A new rule, to be accepted, is to force placeholders in paragraphs to be
    italicized.
