Clarification Proposal for CLHS Section 22.3

Section 22.3 "Formatted Output" of the Common Lisp Hyperspec describes the syntax and semantics of format directives. We believe that the standard is underspecified. We propose to clarify that section, and suggest that Common Lisp implementations conform to the current behavior of CMU-CL, CCL, CLISP, Allegro and LispWorks.
