Yeah, I wanted to add something like this:
if (!self::isDescendant($path, $root)) { return array(); }
But this was problematic for my testing purposes because Filesystem::isDescendant($path, $root) requires $root and $path to actually exist. Would you be open to changing this method to be more general?

What do you think about creating some actual directories inside __tests__/data/ or similar and checking those?
Makes it slightly harder to get the expected values right for stuff above the library, but that seems surmountable to me.

Personally, I find the behavior of Filesystem::isDescendant to be non-obvious and so I think fixing that is the most correct solution. Adding directories in the __tests__/data directory is less obtrussive however.

@epriestley, I haven't had time to extend this further to check for "path is not a descendent of root". Is this fine to push as is?

One possible issue, rest of it looks great to me.

| 759 | This is probably wrong on Windows -- there won't be a leading directory separator on $root, right? Maybe cleaner would be: while ($parts) {
// compute the next thing
// add it to the list
// if we just added the root, break out of the loop
// array_pop parts
