This is to fix sagemath/sagetex#64
where it was reported that the following does not work

\documentclass{article}
\usepackage{sagetex} 
\usepackage{tikz} 

\begin{document}

\sagestr{(polytopes.great_rhombicuboctahedron()).tikz([4,5,6],45,scale=0.75)}

\end{document}

This is due to tikzpicture being put in an argument to \newlabel, which does not accept multiple paragraphs.
