Recursive printing proposal

["BACH::ROBBINS" <robbins%bach.decnet@hudson.dec.com>]

I propose that we add the following macro:

	TOP-LEVEL-PRINT &BODY BODY

The macro is responsible for ensuring that any printing within BODY will
be started as a top level print.

This achieves what having RECURSIVE-P arguments to printing functions would
without breaking existing source code and without requiring any changes to
FORMAT.

I think that while we should specify that the printer automatically handles
depth abbreviation, we should not specify how it is to be implemented.
