Hi, I've been using git for a month now and loving it. This is my  
first ever patch for git using git. I spent sometime to find out why  
the project listing is taking 200s, everytime! I guess that gitweb is  
mostly used to serve bare repositories, which would never encounter  
such problems. It takes .2s, after the patch on my laptop. That's  
1000x improvement for me (on Mac OS X 1.4.10.)
