Newline at the end of text tag should not be rendered when it is followed csharp

[ajaybhargavb]

Related to #485

Example:

In this case,

@using(...)
{
  <div>
...
  </div>
  <input />
}

The newline after </div> should be rendered and the newline after <input/> should not be rendered.

Update: Nuking the newline at the end of all html tags that are followed by csharp breaks scenarios like nested foreach with <ul> and <li>. So doing this change only for <text> tags.

So doing this change only for <text> tags.

Sounds reasonable.
