I think so. I guess the only reason I did not do it because is because the checks are very simple and all 3 conditions that check if the path is absolute return immediately if the condition is true. This is less obvious with the Windows check but is very obvious with the POSIX and stream path checks.

Since these 3 checks (Windows path, POSIX, and stream) are mutually exclusive and not in any way related to the other check after (`if ($useIncludePath && !file_exists($file)) {`), I think all 3 should then be grouped with `if` and `else if` I guess just for readability so readers know they are related but do the same thing.
