--fix-doc-comments not quite stable

[davidmorgan]

Given this input

class Test {
  int x;
  /**
   * Hi.
   */
  int y;
}

dartfmt --fix-doc-comments test.dart produces this output

class Test {
  int x;
  /// Hi.
  int y;
}

but we're not done yet, as running this through dartfmt produces

class Test {
  int x;

  /// Hi.
  int y;
}

Drat, that is a bug.

Closing since we're getting rid of dart format --fix in favor of dart fix: #1153
