title: How to make Rails add line numbers / time stamps to log messages?
body: <p>I use <code>tail -f</code> to display the log file when developing my Rails app.
  It shows the log messages (in color! :), which is great.</p>
  
  <p>But with so much information in the 80-width console, it becomes difficult to track where a certain "set" of log messages started when, say, I clicked on a button to GET a resource.</p>
  
  <p>It would be easier if there was a line number or even a time stamp at the start of each log message/line. This way I could remember that I need to start looking at the log "after line number 2365" or "after 2010/10/10 23:33:23:45".</p>
  
  <p>Is this possible to do? Is there some Rails internal option for this ?</p>
