Explicit documentation of %0c: scanf "%0c" (fun c -> ...) gives access
to the current character without reading it. This is convenient to
continue scanning according to the value of the current character,
without having the burden to add it to the scanning result (if only
possible when you decide to scan %C or %S when c is " or ').
