2007-10-11 change, the child elements here are items not rules. (<xsl:template match="item"): New. (xsl:template match="rule"): Update for new reduced itemset. (xsl:template match="point"): Remove. (xsl:template match="empty"): For consistency with --graph, don't output "/* empty */". * data/xslt/xml2text.xsl (xsl:template match="terminal"): When invoking line-wrap, don't pass a negative value as first-line-length since this won't work with the following changes. (xsl:template name="line-wrap"): Simplify slightly. (xsl:template name="ws-search"): Eliminate recursion. * src/print_graph.c (print_core): Don't print a reduction's lookahead set next to an item whose dot is not at the end of the RHS even if it happens to be associated with the same rule.
