eslint_d.js: Incorrect indentation on fix.

When fixing (or fixing to stdout) eslint_d does not indent fixed lines properly.

Input code:

<template>
  <section class="navbar-container">
    <v-app-bar color="#fff"
      flat
    />
  </section>
</template>

(according to my eslint rules color directive on line 3 must be on separate line ('color' should be on a new line. [Warning/vue/max-attributes-per-line])

and eslint <file> --fix corrects it to:

<template>
  <section class="navbar-container">
    <v-app-bar
      color="#fff"
      flat
    />
  </section>
</template>

while cat <file> | eslint_d --stdin --fix-to-stdout will produce:

<template>
  <section class="navbar-container">
    <v-app-bar
color="#fff"
      flat
    />
  </section>
</template>

Am I doing something wrong or is that a bug?
