latex: add extra '\\' at the end to left align last line (multline)
latex: add extra '\\' at the end to left align last line (multline)

* With --latex, the latex will have an extra ending \\, so I guess it doesn't
  create any problem.

* With --latex-full, this extra ending \\ is necessary because if I don't add
  it, the last line will get center-aligned instead of left-aligned like the
  other lines.
