//! Every `recall` item has one form, from the local index or from Honcho: its header, then its

//! text on one line indented by two spaces, neutralised and capped (M5c spec, section 8). So a
|
||||
//! header written into indexed text, by a fetched page or a forged note, can never begin a line
|
||||
//! of the answer (tip T37). And `local`, which `recall` answers from, gives the items and their

//! label apart. Do not edit.
