Maybe I am misunderstanding the original situation, but I did not think that was the problem. I thought the situation was one where the environment was controlled, but Git still would not do what was wanted (if you did have such a renegade helper, setting GIT_ASKPASS certainly would not help, as it is the fallback). But to answer your question: you can't currently. I would be happy to have a config syntax that means "reset this multi-value config option list to nothing", but it does not yet exist. It would be useful for more than just credential-helper config. -Peff -- 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
