Before doing so, let's take an existing 'int multi_replace' parameter and replace it with a new 'unsigned flags' parameter that can take multiple options as a bit field. Update all callers that specified multi_replace to now specify the CONFIG_FLAGS_MULTI_REPLACE flag. To add more clarity, extend the documentation of git_config_set_multivar_in_file() including a clear labeling of its arguments. Other config API methods in config.h require only a change of the final parameter from 'int' to 'unsigned'.
