Pegdown HARDWRAPS option adds an additional line break when using trailing spaces #56

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

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

line one with line break
line two with line break
line three with line break and 2 trailing spaces
line four at the end

Given result

line one with line break
line two with line break
line three with line break and 2 trailing spaces

line four at the end

My current fix is to change the options to:

options = new MutableDataSet( PegdownOptionsAdapter.flexmarkOptions( Extensions.ALL & ~Extensions.HARDWRAPS ) );
options.set(HtmlRenderer.SOFT_BREAK, "<br/>");
