I think you're right ; I may have been abused by what Adobe Reader
displayed when performing my tests, as I just discovered that, for
whatever reason, it doesn't always reload the pdf file when using
<Ctrl-r>

Using this test document

#===========
* Level 1

** Level 2

*** Level 3

**** Level 4
Text
#===========

the current code produces

%==========
\begin{itemize}

\item Level 4\\
\label{sec-1.1.1.1}

Text
%==========

There's an extra space produced by the \label{} because there's no '%'
at the end of it ; another solution is to move the \label before the
\\
There's also an extra newline before "Text".
Please find attached my second proposal to fix this.

It's not really a problem, it just seems to me like, the less extra
'\n' you see in the output of a LaTeX code generator, the more
confident you can be.
