Extra blank lines appear when using the --silent option.

I propose add a check if (isSilentMode) in the appropriate parts of the code to fix this issue.

function createHumanReporter(process, isSilentMode = false) {
  function print(...lines) {
    if (!isSilentMode) {
      process.stdout.write('  ' + lines.join('\n  ') + '\n')
    }
  }

Need advice on the correctness of this approach.

I could make PR by myself.

This gap is too БЕСИТ 😬
