Invalid regular expression: /^(([^\\]*)|\.$/: Unterminated group

[mrmlnc]

Environment

• Windows 10
• Node.js 12.3.1
• tiny-glob 0.2.6
• globrex 0.1.2

Actual behaviour

const tg = require('tiny-glob/sync');

const entries = tg('{*,./package.json,package.json}');

console.dir(entries, { colors: true });

D:\OpenSource\fast-glob\node_modules\globrex\index.js:42
                    path.segments.push(new RegExp(segment, flags));
                                       ^

SyntaxError: Invalid regular expression: /^(([^\\]*)|\.$/: Unterminated group

Expected behaviour

I see entries.

Thank you! I'm working on a fix for this in the next release.
Are you sure path separators are valid characters inside brace expansions?
