title: Reset Homebrew Formula
body: <p>While trying to install FreeTDS via Homebrew, I ran <code>brew edit freetds</code>.  I edited the file.  I'd like to restore the Recipe file (freetds.rb) to it's orinal state in case I introduced a typo into it.</p>
  
  <p>Is there a way to reset a brew formula file?</p>
  
  <p>Thanks</p>
