Future callers as other commands are built in (am, rebase, sequencer) may find it easier to pass rev-list options to this machinery in already-parsed form. Teach cmd_cherry_pick and cmd_revert to parse the rev-list arguments in advance and pass the commit set to pick_revisions() as a rev_info structure. Original patch by Jonathan, tweaks and test from Ram.
