Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.

Returns `true` if the given string looks like a glob pattern or an extglob pattern. This makes it easy to create code that only uses external modules like node-glob when necessary, resulting in much faster code execution and initialization time, and a bet
