config parsing options: allow one flag multiple times
This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN, 2011-09-27). This commit introduces a change for the users, after this patch you can pass one of the config level flags multiple times: Before: $ git config --global --global --list error: only one config file at a time. usage: ... Afterwards this will work. This is due to the following check in the code: if (use_global_config + use_system_config + use_local_config + !!given_config_file + !!given_config_blob > 1) { error("only one config file at a time."); usage_with_options(builtin_config_usage, builtin_config_options); } With OPT_BOOL instead of OPT_BOOLEAN the variables use_global_config, use_system_config, use_local_config will only have the value 0 if the command line option was not passed or 1 no matter how often the respective command line option was passed.
