    BufferOutputStream: only one user action for the whole file loading
    
    Some applications or higher-level libraries have a ::cursor-moved
    signal, that is emitted only when the number of nested user actions is
    0. So begin/end a user action for the whole file loading prevents
    useless signal emissions.
    
    And as the comment says in the code, a file loading should be seen as
    only one user action.
