When you replace Dscho's "compare 'var' with 'alias.br' that is in
strbuf naively with the "skip-prefix and compare with br" without
changing anything else, i.e.
if (skip_prefix(var, "alias.", &key) && !strcmp(key, data->key))
return git_config_string((const char **)&data->v, key, value);
it would cause the "br" to be fed to git_config_string() and result
in problem reported for "br", not "alias.br".
But this can be trivially fixed by passing "var" instead of "key" to
git_config_string(), no? Am I mistaken?
