expandGlob/expandGlobSync does not handle escaped paths well

**Describe the bug**

`expandGlob`/`expandGlobSync` do not match non-glob path segments with escaped glob characters.

**Steps to Reproduce**

1. File is `[file].txt`
2. Try to use `globSync`/`glob` to find `\[file\].txt`

**Expected behavior**

Should match, but it doesn't.

**Environment**
