3194 | * | |
3195 | * - it locks the config file by creating ".git/config.lock" | |
3196 | * | |
3197 | * - it then parses the config using store_aux() as validator to find | |
3198 | * the position on the key/value pair to replace. If it is to be unset, | |
3199 | * it must be found exactly once. | |
3200 | * | |
3201 | * - the config file is mmap()ed and the part before the match (if any) is | |
3202 | * written to the lock file, then the changed part and the rest. | |
3203 | * | |
3204 | * - the config file is removed and the lock file rename()d to it. | |
