The `key` variable is used by the `get_value()` function for two purposes: - It is used to store the result of `git_config_parse_key()`, which is then passed on to `collect_config()`. - It is used as a store to convert the provided key to an all-lowercase key when `use_key_regexp` is set. Neither of these cases warrant a global variable at all. In the former case we can pass the key via `struct collect_config_data`. And in the latter case we really only want to have it as a temporary local variable such that we can free associated memory. Refactor the code accordingly to reduce our reliance on global state.
