That's what I was trying to document. I think that it makes no sense to use the feature as I had shown above. I had envisioned "unset.variable" to be explicitly typed in on the appropriate place as can be seen in the first two tests but Matthieu had suggested to add tests using git config too. This is when I had discovered these inconsistencies. I can think of two solutions, one leave it as it is and advertise it to be explicitly typed in the config files at the appropriate position or to change the behavior of unset.variable to unset all matching variables in that file, before and after. We could also change git config --add to append at the end of the file regardless the variable exists or not. Which course of action do you think would be best? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
