{@link java.util.Iterator#hasNext()} implementation.
@return True if more lines are availible, false if not.
As this can cause the underlying {@link java.io.InputStream InputStream} to throw
a {@link java.io.IOException IOException} but the {@link java.util.Iterator#hasNext()}
interface does not, false is returned instead of it being rethrown. The exception can be
retrieved via {@link #getIOException()}.
