Re: FORMAT a list

You're pretty-printing the list.

Print it to T rather NIL, and notice that the "?" ends up aligned under
"Watts" -- that is, that it wrapped the line and indented it so that the
elements of the inner list line up.

Try :
(let ((*print-right-margin* 60)
      (zz '( "SELECT" "this, that" "FROM" "table" "WHERE" "this" "LIKE"
"\"foo%\"" "OR"  ("watts" ">" 42 "AND" "jules" ">" "?"))))
  (format t  "~&~{~A~^ ~}" zz))

and then play with the margin to see the effect.
