Two optional cleanups here:
1. We don't need to call config_key_is_valid when using a callback. We
only needed that to prevent the configset machinery from issuing a
warning. It does save us reading the config entirely when the
program name is syntactically invalid as an alias, but that's a
pretty rare case.
2. Now that we're not using the configset machinery, we don't need to
have the alias name as a full string. Instead of using the strbuf,
we could just pass the "alias" string itself and do:
if (skip_prefix(var, "alias.", &key) && !strcmp(key, data->key))
in the callback.
I don't think either is a big deal, though.
