From 7aa651a6a4496d848f86de9b1e6b3a003256a01f Mon Sep 17 00:00:00 2001

Subject: Reindent to two spaces per level. Remove vi: directives that haven't
 worked right in years (ubuntu broke its' vim implementation). Remove trailing
 spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation
 with new coding style.

The actual code should be the same afterward, this is just cosmetic refactoring.
