Next revision of my patch series to improve error handling on
git_config_set. Only three small changes to v5 [1], thanks for
pointing these out:

    - fixed missing conversion of git_config_set_or_die in
      compat/precompose_utf8.c
    - fixed indentation in install_branch_config
    - improved advise message to give the complete command for
      fixing up the upstream configuration, including the actual
      tracking branch
