Formatter: Adding whitespace before ' that follows Ruby tag

[ron-shinall]

Using Herb 0.8.0...when there is an ' beside a Ruby execution tag the formatter adds undesirable whitespace before it.

Input:

      <p>
        Lorem <%= letter.patient.first_name.titlecase %>'s ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
      </p>

Output:

      <p>
        Lorem <%= letter.patient.first_name.titlecase %> 's ipsum dolor sit amet, consectetur adipiscing elit, sed do
        eiusmod tempor incididunt ut labore et dolore magna aliqua.
      </p>

Expected:

      <p>
        Lorem <%= letter.patient.first_name.titlecase %>'s ipsum dolor sit amet, consectetur adipiscing elit, sed do
        eiusmod tempor incididunt ut labore et dolore magna aliqua.
      </p>
