We could modify Fread to optionally return character positions in the
stream of the components of the form it reads, perhaps by recursively
substituting every form with (form . position), in the way
Fread_from_string does.  This would be generated by an optional
argument to Fread, or perhaps a new Fread_with_positions function.
