Supporting Junio's claim, there is a function called git_default_config() which checks and sets a whole load of config values which may or maynot be relevant to the codepath that called it. (branch.autosetuprebase is a part of it) So an error may occur printing a seemingly unrelated config value as the malformed variable as happened in your case. There are currently 72 callers of git_default_config() in the codebase, so a malformed config value breaks most of git commands. The only path to correct this behavior would be either correct the config variable in the file or we could decouple the huge monolithic function that git_default_config() has become and use the git_config_get_value() in the code paths that really need them. This part is doable, albeit slowly. All the config variables in git_default_config() can be rewritten using the new non callback based functions easily as demonstrated in an earlier RFC patch. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
