Is there no atom where %(atom:) was previously accepted and did something meaningful that this may break? Looking at the manpage and code, I don't see any, so for what it's worth, this is Reviewed-by: Jonathan Nieder <jrnieder@xxxxxxxxx> but for next time, please remember to discuss regression risk in the commit message, too.
