para settings of nested lists are different if block code is used

[u-fischer]

(extracted from issue #119 for better discussion)

With the new block code lists nested inside a center or similar environment behave differently than with standard LaTeX. While standard LaTeX in most cases resets para settings (the exception are setting from \raggedleft), the new code passes them on.
