title: Revert local changes in fossil
body: <p>How do I clean/revert/undo local, un-commited changes in a <em>single</em> source file with Fossil?</p>
  
  <p>The <a href="http://fossil-scm.org/index.html/help?cmd=clean" rel="noreferrer">clean</a> command looks to me like it should do the trick, but no, the local changes are still there.  I am looking for the same effect as "git checkout filename.c" would have.</p>
