* NOTES
* Every node type that can appear in stored rules' parsetrees *must*
* have an output function defined here (as well as an input function
* in readfuncs.c). For use in debugging, we also provide output
* functions for nodes that appear in raw parsetrees, path, and plan trees.
* These nodes however need not have input functions.
