Tests broken on Windows: "even with special characters"

[KoltesDigital]

While inspecting for a bug, I tried running the tests. These errors happens on both cmd and cygwin, with Node.js 4.2.1 on Windows 8.1. D:\Project\ has no particular rights.

D:\Project\node_modules\mv> npm t

> mv@2.1.1 test D:\Project\node_modules\mv
> mocha test/test.js --reporter spec



  mv
    √ should rename a file on the same device
    √ should not overwrite if clobber = false
    √ should not create directory structure by default
    √ should create directory structure when mkdirp option set
    √ should work across devices (38ms)
    1) should work across devices, even with special characters
    √ should move folders (56ms)
    √ should move folders across devices (45ms)
    2) should move folders across devices, even with special characters


  7 passing (342ms)
  2 failing

  1) mv should work across devices, even with special characters:
     Uncaught Error: ENOENT: no such file or directory, open 'D:\Project\node_modules\mv\test\a-*'
      at Error (native)

  2) mv should move folders across devices, even with special characters:
     Uncaught Error: ENOENT: no such file or directory, open 'D:\Project\node_modules\mv\test\a-*'
      at Error (native)



npm ERR! Test failed.  See above for more details.

It also doesn't work with Node.js 0.12.7 on the same machine.
