I added this:

   /*    * We use the hopefully-safely-small value of 100kB as the compiled-in    * default for max_stack_depth.
InitializeGUCOptionswill increase it if    * possible, depending on the actual platform-specific stack limit.    */
 

although I don't entirely see the point.  We are certainly not going to
comment every variable whose compiled-in default gets changed by later
processing.
