[PATCH 06/10] revert: Separate cmdline parsing from functional code

From: Ramkumar Ramachandra <artagnon@gmail.com>

Message-ID: <1306333025-29893-7-git-send-email-artagnon@gmail.com>

Make cmd_cherry_pick and cmd_revert call parse_args and parse all the command-line arguments into an opts structure before sending it off to a simplified pick_commits function. pick_commits, in turn will set up the revision walker and call do_pick_commit in a loop- later in the series, it will serve as the starting point for continuation.
