+ * Fix bug regarding variants. Tags with prefix "var" was incorrectly
+ * interpreted as "start of variants". Now, only "var" indicates such
+ * start.
+ * Cleaned up data1_read_node so tag names and variant names are
+ * copied and not pointed to by the generated data1 tree. Data nodes
+ * still point to old buffer.
