title: Escape quotes is not working in spark 2.2.0 while reading csv
body: <p>I am trying to read my delimited file which is tab separated but not able to read all records.</p>
  
  <p>Here is my input records:</p>
  
  <pre><code>head1   head2   head3
  a   b   c
  a2  a3  a4
  a1  "b1 "c1
  </code></pre>
  
  <p>My code:</p>
  
  <pre><code>var inputDf = sparkSession.read
                    .option("delimiter","\t")
                    .option("header", "true")
  //                  .option("inferSchema", "true")
                    .option("nullValue", "")
                    .option("escape","\"")
                    .option("multiLine", true)
                    .option("nullValue", null)
                    .option("nullValue", "NULL")
                    .schema(finalSchema)
                    .csv("file:///C:/Users/prhasija/Desktop/retriedAddresses_4.txt")
  //                  .csv(inputPath)
                    .na.fill("")
  //                  .repartition(4)
  
                    println(inputDf.count)
  </code></pre>
  
  <p>Output: </p>
  
  <pre><code>2 records
  </code></pre>
  
  <p>Why it is not returning 3 as count?</p>
