We usually try to avoid booleans for selection among options, even if there is currently only one useful option. That way, it makes it easier to extend later when another option presents itself. So having "status.format" that you could set to "short", "long", or "porcelain" would make more sense (although "short" is likely to be the only useful one currently).
And then we can have a separate boolean like "status.branch" to show the branch by default when showing short format. That would would naturally extend to more booleans as other options are added (Phil Hord's recent "show tree state" patches come to mind).
We also need to consider the impact of options on scripts. I think status.format should be OK, since any script calling "git status" would have to explicitly pass "--porcelain" already, which would override this option. But we would want to make sure that "status.branch" would not affect the porcelain.

It would need documentation, and tests would be good both to make sure the feature works, but also to demonstrate that it does not break --porcelain.

if (git_config_bool(k, v)) {
status_format = STATUS_FORMAT_SHORT;
s->show_branch = 1;
}
else {
/* what do we do when it is false? */
}
return 0;If we follow my suggestions above, then it would be more like:
if (!strcmp(k, "status.format")) {
if (!v)
return config_error_nonbool(k);
return parse_status_format(v, &status_format);
}
if (!strcmp(k, "status.branch")) {
s->show_branch = git_config_bool(k, v);
return 0;
}but that would still have to resolve the setting of show_branch when --porcelain is in use. I think you would need to store the config-derived value separately, and then only fill it into s->show_branch if no value was given on the command-line _and_ we are not showing the porcelain format.
