title: Can I 'git commit' a file and ignore its content changes?
body: <p>Every developer on my team has their own local configuration.  That configuration information is stored in a file called <code>devtargets.rb</code> which is used in our rake build tasks. I don't want developers to clobber each other's devtargets file, though. </p>
  
  <p>My first thought was to put that file in the <code>.gitignore</code> list so that it is not committed to git.</p>
  
  <p>Then I started wondering: is it possible to commit the file, but ignore changes to the file? So, I would commit a default version of the file and then when a developer changes it on their local machine, git would ignore the changes and it wouldn't show up in the list of changed files when you do a git status or git commit.</p>
  
  <p>Is that possible?  It would certainly be a nice feature...</p>
