[PATCH] ox-latex.el/org-latex--make-option-string: Surround option string with braces if it includes brackets

[Markus Huber]

lisp/ox-latex.el (`org-latex--make-option-string'): If `value' of a `pair' from 
`options' contains a bracket
the whole `value' is surrounded by braces.

In case of LaTeX export using listings the dialect of a language (e.g. 
[LaTeX]TeX) is surrounded by brackets. For inline
source blocks all options end as optional argument to \lstinline between 
brackets which breaks the LaTeX parser.
