scans the contents of a here document including the line containing the delimiter. Returns the pretoken containing the contents of the here document. As a side effect, assigns the contents of the here document to the reference that was registered by push_here_document_operator.
Are we currently reading a sequence of here documents?
Must the next word be a here document delimiter?
