title: Git Warning: LF will be replaced by CRLF
body: <p>I am using Git gui. I see this error for several files in a folder. I have two choice buttons - <code>Unlock index</code> and <code>Continue</code>. I don't understand what the buttons do. I saw other SO posts which tell
  me to ignore the warning, but they don't mention how to do it in GUI. Please tell me which button I should press and why.
  Thanks.</p>
  <p>Here is the error message sample -</p>
  <blockquote>
  <p>Updating the Git index failed.  A rescan will be automatically started to resynchronize git-gui.</p>
  </blockquote>
  <blockquote>
  <p>warning: LF will be replaced by CRLF in gen/com/click4tab/pustakalpha/BuildConfig.java.
  The file will have its original line endings in your working directory.
  (repeat above messages for other files)</p>
