`(in-hole E hole)` typesets as just `E`

[florence]

In the program:

#lang racket
(require redex/reduction-semantics
         redex/pict)
(define-language L
  (E ::= hole (add1 E)))
(render-term L (in-hole E hole))

I get back a pict containing just E, rather than E[[]], which I would expect.

makes this seem like a deliberate choice. However I find myself needing wanting typeset E[[]]=E in an explanation, which I currently can't do.

I think that was probably a bad choice on my part and am reluctantly okay with a backwards incompatible change here.
