Title:
  echo 1 | sort | head -n0: sort: write failed: 'standard output':
  Broken pipe

Status in rust-coreutils package in Ubuntu:

Status in rust-coreutils source package in Questing:

Bug description:
  dpigs produces its output, then shows an error:

      sort: write failed: 'standard output': Broken pipe

  dpigs end with a 'sort | head' pipeline. This error is due to sort's
  new behaviour in rust-coreutils when being passed into a pipe that's
  closed mid-write, which is exactly what head does.

  Minimally, this is reproducible with:

      $ echo 1 | sort | head -n0
      sort: write failed: 'standard output': Broken pipe

  This is either a latent bug in dpigs or a regression in rust-
  coreutils.
