Opening square bracket after new line results in invalid LaTeX code

A new line ist mapped to

\\*

The full syntax specification of this command is

\\[*][extra-space]

Hence, the following XWiki fragment

[Gupta98] Frederic Gupta etal, 1998, Fractal symmetries in hot soups
[Kracke99] ... 

maps to the LaTeX code fragment

... Fractal symmetries in hot soups\\*[Kracke99] ...

that will no compile since the expression in square brackets is assumed to be a number.

Hence, a new line should be better mapped to

\\*[0pt]
