Various LaTeX packages may redefine \\, so low level \cr might be not 
enough. Actually I do not like that \\ does not have a robust 
counterpart with no optional arguments.

It is better to make `org-latex-line-break-safe' a user option instead 
of a constant.

For a record. Unlike \\, \newline does not have optional argument, but
{\centering a\\b\par} and {\centering a\newline b\par} are not equivalent.

I hope, \empty will behave better than \relax.
