The function `git_config_parse_parameter` is responsible for parsing a `foo.bar=baz`-formatted configuration key, sanitizing the key and then processing it via the given callback function. Given that we're about to add a second user which is going to process keys in such which already has keys and values separated, this commit extracts a function `config_parse_pair` which only does the sanitization and processing part.
