'#' and 'library' can't be separated by a whitespace

The specification defines the library directive as
libraryName:
   “#” “library” “(” stringLiteral “)” “;”
;

From this production '#' and 'library' are two different tokens and thus can be separated with a whitespace. However, only frog allows this. In DartVM and DartC separation of '#' and 'library' results in a compile-time error:

library('l');

//VM: Unrecognized library tag # library('l');
//DartC: Unexpected token 'ILLEGAL' (expected end of file)
       //1: # library('lib');
main() {
  print('Ok');
}

The same problem is for all other directives: #import, #source, #resource.

Tested on r4602. OS: Ubuntu 10.04.

Gilad I know we talked about this when looking at the spec the other day, please update the spec to not allow the whitespace between # and the library tag.
