Brace expansion with single words in it is quite useless - `HEAD@{0}` expanding to `HEAD@0` breaks git. So we complicate the rule slightly - if there is no variable expansion or "," inside of braces, they are just treated as literal braces. Note that this is technically backwards-incompatible, because echo foo{0} will now print `foo{0}` instead of `foo0`. However that's a technicality because the braces were literally useless in that case. Our tests needed to be adjusted, but that's because they are meant to exercise this in weird ways. I don't believe this will break any code in practice. Fixes #5869.
