----------------------------------------------------------------------
I've added a fix in revision 1551220.
- the parser doesn't complain about negative offsets any more, as those
represent object numbers (type2 entries in a xref object stream)
- the parser now unreads the right amount of bytes if the keyword is splitted
into 2 halfs
