title: how to make `git add` work with `xargs`
body: <p>xargs works with dos2unix but it doesn't work with git add.
      Why?</p>
  
  <pre><code>$ git status -s -uno | sed -n 's/^...//p' | xargs dos2unix -u
  dos2unix: converting file Server.C to UNIX format ...
  dos2unix: converting file Proxy.C to UNIX format ...
  dos2unix: converting file Proxy.H to UNIX format ...
  
  $ git status -s -uno
   M Server.C
   M Proxy.C
   M Proxy.H
  
  $ git status -s -uno | sed -n 's/^...//p'
  Server.C
  Proxy.C
  Proxy.H
  
  $ git status -s -uno | sed -n 's/^...//p' | xargs git add
  xargs: git: No such file or directory
  </code></pre>
  
  <p>What should I do so that the <code>xargs</code> works with <code>git add</code>?</p>
