[RFC PATCH v2 00/13] example implementation of revwalk tutorial

Since r1, made some significant changes.

 - Added a commit for counting the 'omitted' list, to match the new
   section added to the tutorial.
 - Added significant comments to allow the sample to better stand on its
   own.
 - Fixed style issues (die() formatting, etc)
 - Distinguished between human- and machine-readable output with
   trace_printf() and printf(), to turn the command into plumbing.
 - More changes as mentioned in the tutorial patch.

Thanks.
 - Emily
