Don't indent binary operators

[jhaber]

Fixes #306

I was wondering whether this indentation is desirable for other binary operators, for example >, however I think it's better not to start creating heuristics for different binary operators. This also appears to match prettier-js behavior (example below)

Input:

function example() {
  const greater = someReallyLongExceptionallyUnbelievablyLongIntegerName > anotherReallyLongExceptionallyUnbelievablyLongIntegerName;
  const blah = "asldjoewimqwioemwqoiewoiqjeoiamdoimwqioejwqoimdasoidmoqwie" + "qweinaoidnoiqwneoiwqjeoiwqjoiasndoisamdoiqwmeiowqjoieoi" + "qwewhqenwoniosadjoienrmnmziojqoirjqwoeiqowewq";
}

Output:

function example() {
  const greater =
    someReallyLongExceptionallyUnbelievablyLongIntegerName >
    anotherReallyLongExceptionallyUnbelievablyLongIntegerName;
  const blah =
    "asldjoewimqwioemwqoiewoiqjeoiamdoimwqioejwqoimdasoidmoqwie" +
    "qweinaoidnoiqwneoiwqjeoiwqjoiasndoisamdoiqwmeiowqjoieoi" +
    "qwewhqenwoniosadjoienrmnmziojqoirjqwoeiqowewq";
}

Yes, you are right, the issue I fixed with the code you removed should have been fixed otherwise, and it is ok now I think!
