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.
