+//

+//     Applied only outside fenced code blocks.
+//
+//  4. fixBlockquoteHardBreaks: inserts a blank blockquote line (">") between
+//     consecutive blockquote content lines so create-doc preserves line breaks.
+//     Applied only outside fenced code blocks.
+//
+//  5. fixTopLevelSoftbreaks: inserts a blank line between adjacent non-empty

+//     consecutive list items / continuations are not separated.
