title: Where do the settings in my Git configuration come from?
body: <p>I've noticed that I have two listings for <code>core.autocrlf</code> when I run <code>git config -l</code></p>
  
  <pre><code>$ git config -l
  core.symlinks=false
  core.autocrlf=false
  color.diff=auto
  color.status=auto
  color.branch=auto
  color.interactive=true
  pack.packsizelimit=2g
  help.format=html
  http.sslcainfo=/bin/curl-ca-bundle.crt
  sendemail.smtpserver=/bin/msmtp.exe
  diff.astextplain.textconv=astextplain
  rebase.autosquash=true
  user.name=name
  user.email=email@example.com
  core.autocrlf=true
  </code></pre>
  
  <p>Those last three (from user.name down) are the only ones in my <code>C:\users\username\.gitconfig</code> file. Where are all of the other ones coming from?  Why is core.autocrlf listed twice?</p>
  
  <p>This is with MSysGit 1.8.3, and I also have Sourcetree installed (Windows&nbsp;7). In Sourcetree I have unchecked the "Allow Sourcetree to modify your global Git config files"</p>
