Hi Junio, I had add a new c function ` git_config_bool_or_str()` to support get the configured value for true/false/auto with git. It will make the `mergetool/meld` only calling `git config` once for getting the `useAutoMerge`. Please review the [PATH v16], thanks. https://lore.kernel.org/git/pull.781.v16.git.git.1594544903477.gitgitgadget@xxxxxxxxx Regards Lin
