+{- When a comment is not preceded with elements on the same line,
+   they are indented as the elements in the enclosing AST node or
+   braces/parenthesis/brackets.
+   If it is between AST nodes, it is indented as the following
+   node.
+   If the end-of-file follows, then indent to column 0.

+   the comment lines.
