Fix indenting within function literal

[aengelberg]

There appears to be a bug that when list-indent is called in a #(...) form, the # character isn't accounted for, making the inner forms look one space short. Note that this bug only comes into play when the inner form doesn't match any custom indent rules.

;; Before
(do
  (a-thing))
#(do
   (a-thing))
(foo
  (bar))
#(foo
  (bar))   ; <-- !!!

;; After (with my fix)
(do
  (a-thing))
#(do
   (a-thing))
(foo
  (bar))
#(foo
   (bar))
