I was investigating https://github.com/gulpjs/glob-parent/blob/main/index.js#L26-L29 in relation to the test suite and I think the pattern is completely wrong.

For example: 'path/\\[bar]' is matched by that pattern, but the "enclosure" ([bar]) doesn't contain any path separator.

My gut feeling is that the [\/]* pattern is supposed to be [\/]+ so that it matches only if there's one or more / inside the enclosure, instead of 0 or more. But I have no idea... maybe @paulmillr or @es128 have an idea 🤞
