    buildhistory-diff: operate from buildhistory directory
    
    If the cwd is named "buildhistory" and the user hasn't specified an
    alternative path on the command line, then assume that the current
    directory is the buildhistory directory. This makes it easier to run
    buildhistory-diff and also interact with the buildhistory git repository
    as you no longer have to jump into the buildhistory directory and up to
    the parent again when doing so.
