Core pretty-printer doesn't print # on unboxed literals

I just noticed that Core pretty printer produces something like this (this is part of expected output for T3772 in testsuite):

    case GHC.Prim.<=# n# 0 of _ {
      __DEFAULT -> xs n#;
      1 -> GHC.Tuple.()
    }

Both 0 (in scrutinee) and 1 (one of branch alternatives) are unboxed values, so they should be printed as 0# and 1# respectively. I haven't checked whether unboxed literals of other types (Word, Double, Float) are printed in that way, but I would guess that yes.
