I wonder if we shouldn't have something slightly more general, such as
a function which returns nil for "normal code" nodes and non-nil for
"textual" nodes, in which case it could additionally return info such as
whether it's rather like a comment or rather like a string or maybe some
information about how to insert/remove a linebreak from within it (in
case they need to be escaped somehow, or for line-comments).
