    Hi,

    I think the example below reveals an error in the handling of margin-left and
    margin-right. According to section 10.3.3 of the CSS2 specification the "auto"
    values should be treated as "0", because the width is also set to "auto" (didn't
    have to be defined explicitly). Both blocks should therefore be treated equally,
    but they aren't. It seems to me that for the first block, space-start and space-end
    semantics were applied.
