Added HW after fixing git issues.

By starting with a string with spaces here, you ensure that `OneLineTag` sub-classes like `Title` and `H` render with these extra spaces after the tag name.  Look at this fragment of output from running your script:

```html
        <head>

            <meta charset = "UTF-8">

            <title  >
                PythonClass = Revision 1087:
            </title>
        </head>
        <body>

            <h2  >
                PythonClass - Class 6 example
            </h2>
```

You see that extra space after the `title` and `h2` tag names?  That's the result of this bug.
