Snippets do not preserve indentation

[jeanlucthumm]

Snippet generation does not preserve the indentation level of the text that was typed. For example, take the begin snippet. We want this:

\begin{document}
    \begin{equation}
    f(x)
    \end{equation}
\end{document}

But instead we get this:

\begin{document}
    \begin{equation}
    f(x)
\end{equation}
\end{document}

Great work, fixes this important problem for me. ~~Why is there no PR yet? :)~~ Nevermind, actually there is. Hope to see it in master soon.
