  26  * line and col are the line and column number of the next character (1-based).
  27  * start_line and start_col are set by isl_stream_getc to point
  28  * to the position of the returned character.
  29  * last_line is the line number of the previous token.
  30  *
  31  * yaml_state and yaml_indent keep track of the currently active YAML
  32  * elements.  yaml_size is the size of these arrays, while yaml_depth
  33  * is the number of elements currently in use.
  34  * yaml_state and yaml_indent may be NULL if no YAML parsing is being
  35  * performed.
  36  * yaml_state keeps track of what is expected next at each level.
  37  * yaml_indent keeps track of the indentation at each level, with
  38  * ISL_YAML_INDENT_FLOW meaning that the element is in flow format
  39  * (such that the indentation is not relevant).
