All input lines now enter the chunklist with sequential indices, and header lines are excluded from matching via Pattern.startIndex and PassMerger offset. This allows the number of header lines to be changed at runtime with change-header-lines(N), transform-header-lines, and bg-transform-header-lines actions. - Remove EvtHeader event; header items are read directly from chunks - Add startIndex to Pattern and PassMerger for skipping header items - Add targetIndex field to Terminal for cursor repositioning across header-lines changes Close #4659
