Signature of Parser::GetNextDocument

It would probably be nice if, like getline with stdlib iostreams,
Parser::GetNextDocument would return a bool to indicate if there is still a
document available, so you'd be able to 

while (parser.GetNextDocument(doc)) {
  // do something with doc
}

instead of 

while (parser) {
  parser.GetNextDocument(doc);
  // ...
}

A patch is attached, seemed straightforward if I didn't miss anything ...
