Issue #9648 has been updated by Usaku NAKAMURA.

Backport changed from 2.0.0: UNKNOWN, 2.1: UNKNOWN to 2.0.0: DONTNEED,
2.1: DONTNEED

I've tested on 1.9.3-p545, 2.0.0-p451, 2.1.1 and found they are ok.
This problem is only with trunk.

`Dir.glob('../*')` shows unexpected result if current directory is a
symbolic linked directory on Windows.
This issue seems to be introduced by r44802.

The following is a test case.
