[ 1850772 ] XQ: [preceding and following]-sibling:: bug
http://sourceforge.net/tracker/index.php?func=detail&aid=1850772&group_id=56967&atid=482468
in case the "unique items" optimization in the child-step implementation is
applied,
we need to make sure that we keep the "end_ctx" BAT aligned with the "iter" &
"item" BATs.
... test needs to be adapted to the Stable version of pathfinder, first, before
it can be added ...
