Function contack::read_write::escape::fold_line

pub fn fold_line<T>(string: T) -> String where
    T: Deref<Target = str>, 

This is supported on crate feature read_write only.

This will fold a line. This is run when generating a component.

Line folding requires that every 80 octets the line is folded. Unforunately that is a pain to do so I just to it every 75 unichars.
