Pegdown HARDWRAPS option adds an additional line break when using trailing spaces
*Created by: Elmervc*
When using the following option configuration:
`new MutableDataSet( PegdownOptionsAdapter.flexmarkOptions( Extensions.ALL ) )` ,
the parser/renderer adds 2 line breaks instead of one when using 2 trailing spaces followed by a line break.
### Example markdown
```markdown
line one with line break
line two with line break
line three with line break and 2 trailing spaces
line four at the end
```
#### Expected result
<p>line one with line break<br> line two with line break<br> line three with line break and 2 trailing spaces<br> line four at the end</p>
#### Given result
<p>line one with line break<br> line two with line break<br> line three with line break and 2 trailing spaces<br> <br> line four at the end</p>
-----
My current fix is to change the options to:
```java
options = new MutableDataSet( PegdownOptionsAdapter.flexmarkOptions( Extensions.ALL & ~Extensions.HARDWRAPS ) );
options.set(HtmlRenderer.SOFT_BREAK, "<br/>");
```
