You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: showdoc.m
    path of file: ./repos/bspm/thirdparty/spm8/matlabbatch/@cfg_repeat
    
    the code of the file until where you have to start completion: function str = showdoc(item, indent)

% function str = showdoc(item, indent)
% Display help text for a cfg item and all of its options.
%
% This function is identical for all cfg_intree classes.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
