Hard line breaks and trailing spaces

If you look at the AST for this example you’ll notice that the first line has trailing spaces. My understanding from 4.8 is that leading and trailing spaces for lines in a paragraph are to be stripped – but that’s not the case here.

I think that perhaps the reference implementation is treating the spaces before \ as interior spaces and therefore leaving them alone. Shouldn’t they be stripped since the \ isn’t “really” the last character in the line?

Hi, any thoughts on this?
