Contract violation when using prefab struct datums w/linebreaks in racketblock

[otherjoel]

This program:

#lang scribble/manual

@racketblock[
  '#s(doc
   (1
    2
    3))]

Results in:

syntax-e: contract violation
  expected: syntax?
  given: #f

Compare this version, which does not produce any errors:

@racketblock[
 '#s(doc (1
          2
          3))]

I would expect that the first work as well as the second, since both forms are valid when used directly in racket/base.
