Subject: Bugfix: NullPointerException in AreaAdditionUtil in a table-cell
 spanning multiple pages and with a marker. Note: This is a hack to avoid the
 NPE. A problem remains. The markers will not be added if the first/last
 conditions cannot be determined.

git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk@407614 13f79535-47bb-0310-9956-ffa450edef68
