title: Why does git rm not work?
body: <p>I am trying to remove a dir from the remote git repository. However, when I do:</p>
  
  <pre><code>$ git rm --cached QTNNSimplePredictTensorflowDataGen_HLD_240_DOI_1_PG_1_WD_0.0_SOT_allpair_20150701_20160630_TE_442_DOR_0.09_AF_sigmoid

  <p>I get a fatal error. Any idea?</p>
