;;Basically, the serializer makes the input preserve the newlines
;;and adds the string character "\n<EOF>\n" by the end.
;;I guess it could send "\x04" instead to signal a real EOF,
;;but I would need to check if that does not kill the pipe...
;;An alternative approach is to use the input-done? command
;;from TeXmacs, but, at the time of this writing, it did not work.--A
