When we're skipping comments but retaining newlines, we need to do some slight-of-hand because single-line comment tokens contain the newline that terminates them (for simpler handling of lead doc comments) but our parsing can be newline-sensitive. To allow for this, as a special case we transform single-line comment tokens into newlines when in this situation, thus allowing parser code to just worry about the newlines and skip over the comments.
