From: Jonathan Nieder <jrnieder@xxxxxxxxx>
Since 7e2bfd3f (revert: allow cherry-picking more than one commit,
2010-07-02), the pick/revert machinery has kept track of the set of
commits to be cherry-picked or reverted using commit_argc and
commit_argv variables, storing the corresponding command-line
parameters.
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. So, 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 "struct rev_info".
