On a maybe related note, should there be a SLIME version of
*print-gensym*? For a while I had a small change to my local
swank.lisp to define (and use at seemingly appropriate places)
*slime-pprint-gensym* which I set to NIL in my .swank.lisp so macro
expansions would look more like real code. Your new code made that
variable obsolete--i.e. it needs to be integrated into
define-printer-variables but in the 15 seconds I spent looking at your
change I didn't see exactly what I should change to reitroduce such a
variable. At any rate, perhaps define-printer-variables shoud just go
ahead and create variables for *all* the printer control variables. It
seems that define-printer-variables doesn't define variables
corresponding to:

  *print-array*
  *print-base*
  *print-gensym*
  *print-lines*
  *print-miser-width*
  *print-radix*
