reminder -- eight spaces != tab

[Paul Rohr]

Sigh.  After poking around in some more code recently, I finally understand 
what Jesper, Aaron, and others have been complaining about...

Without naming any names, it's quite clear that somebody's got their editor 
configured to insert eight-space indents instead of tabs.  To quite from the 
source code guidelines:

  "14.  Indents are 4 spaces or 1 tab.  Tabs are 4 spaces."

Please fix this.  

Thanks,
Paul
