Sorry for not finding it myself, but where can I read the exact correspondence
like 9 == \rightskip? I just did a pdf search on 'rightskip' and didn't find it.

(I'm trying to understand why, with latex, I have a glude node of subtype 2 at
the beginning of paragraphs with the article class, but not with minimal.)

Thanks,
Manuel.
