The reason is that so far, i judged the average quality of man(7) documents in the wild low enough that warning about this minor detail felt too noisy to me. In typical man(7) documents, there are bigger fish to fry. In mdoc(7), on the other hand, it doesn't matter where the blank line occurs - before the preamble macros, among the preamble macros, or in the document body. The mandoc(1) program warns in any case. Actually, a blank line *before* the body even causes two warnings: "blank line in fill mode" and "content before first section header". Yours, Ingo
