You misunderstood me, maybe I didn't explain this very well. The
document doesn't literally contain "\\<newline>".  For me your
example results in the following output.

#+BEGIN_SRC latex
  \begin{document}

  \maketitle
  
  \section{Head
  \label{sec-1}
  The first sentence. \\
  The second sentence.
  % Emacs 24.3.1 (Org mode 8.2.6)
  \end{document}
#+END_SRC

Note the "\\" after "The first sentence".  That is what I want to get
rid of.

While producing said output I glanced at the org file's header and saw
the following line:

#+OPTIONS: \n:t

After removing that line, everything works as expected.  I cannot
remember putting this option there and thus did not think of looking for
a cause in the header of my org file.

Thank you anyway for you response!

Kind regards,
