Brace expansion matches single item

[mojavelinux]

According to the braces library, braces expansion should not match a single item like {foo}. However, picomatch does interpret this expression.

braces:

braces('{foo}')
//=> ['{foo}']

picomatch:

picomatch.parse('{foo}').output
//=> '(foo)'

Compare that to when there are multiple items:

braces('{foo,bar}')
//=> ['(foo|bar)']
picomatch.parse('{foo,bar}').output
//=> '(foo|bar)'

It seems to me like the behavior should match in both cases.

I also find this comment from the README confusing:

Picomatch does not do brace expansion.

Based on my observations, picomatch appears to support all sorts of brace expansion.

Picomatch does not do brace expansion.

Brace expansion is not the same as brace matching.

Expansion does this: {a,b,c} => ['a', 'b', 'c'].

braces expansion should not match a single item like {foo}.

Agreed, this is a bug. Thanks for creating the issue.

Aha! That makes sense. Thanks for clarifying.
