There is a empty line at the beginning when there is no error

[xuchunyang]

When M-x esup is finished, there is no error detected. In buffer *esup*, the first line is empty and point is at the beginning, n (esup-next-result) doesn't work here and says

funcall-interactively: Beginning of buffer

The following fix the issue by not insert the empty line when there is no error.
