Issue: DEFPACKAGE (version 5)

[Jon L White <jonl@lucid.com>]

I approve of this version.

I also like :internal, and had intended to bring it up before.  The comment 
about uselessness:
    - the change to :IMPORT-FROM and :SHADOWING-IMPORT-FROM to call
      FIND-SYMBOL instead of INTERN inadvertently made them useless,
      since there is no way to assure that non-exported, non-shadowed
      symbols exist.  . . . 
is a bit overly pessimistic here, since internals symbols are created 
merely by reading files.  But there's no question that defpackage should 
have a way of creating internal non-exported, non-shadowing symbols.
