In order to demonstrate how to create grep filters for revision walks, filter the walk performed by cmd_walken() to print only commits which are authored by someone with a gmail address. This commit demonstrates how to append a grep pattern to a rev_info.grep_filter, to teach new contributors how to create their own more generalized grep filters during revision walks.
