The following commit has been merged in the upstream branch:

    (#5171) Made filebucket able to perform diffs
    
    It is now possible to ask the filebucket to diff two files using a URL
    of the form:
    
    https://puppet/production/file_bucket_file/md5/{first file hash}?diff_with={second file hash}
    
    The returned diff is a string, the output of the "diff" command.
