maybe bug in write()

[zh99998]

i'm trying to upload file to my repo

github = new Github
  username: "zh99998",
  password: <hidden>,
  auth: "basic"

repo = github.getRepo('zh99998', 'test')

repo.write 'master', '/README.markdown', 'test1', 'test2', (err)->
  console.log err

then it logs out null, and see Network, all are 200 OK / 201 Created, seems all well, when i go to github and see that repo, the commit is successful, but there's nothing in this commit, and file is not modified.

like this:
zh99998/test@d292be1

[zh99998]

oh sorry, there‘s no "/"
