Why the complicated logic flow? Also, why is strbuf 'update' needed?
I'd have expected to see something simpler, such as:
} else if (!strcmp(item.buf, "update")) {
if (!value)
ret = config_error_nonbool(var);
else if (!me->overwrite && ...)
warn_multiple_config(...);
else {
free((void *)submodule->update);
submodule->update = xstrdup(value);
}
}
