I'm not completely sure, but I don't think you can use scope selectors 
when defining folds.
But note that the if occuring in the comment might match the 
foldstartmarker, but there would have to be a matching foldstopmarker at 
the same indent level to make it a fold. So I don't think that it would 
show up as a fold.

I think that if you really want this to work properly, you'll have to 
expand the match more to not only match "if", but also the pattern after it.
