This makes it possible to pass many commits or ranges of
commits to "git cherry-pick" and to "git revert" to process
many commits instead of just one.

In fact commits are now enumerated with an equivalent of

	git rev-list --no-walk "$@"

so all the following are now possible:

	git cherry-pick master~2..master
	git cherry-pick ^master~2 master
	git cherry-pick master^ master

The following should be possible but does not work:

	git cherry-pick -2 master

because "git rev-list --no-walk -2 master" only outputs
one commit as "--no-walk" seems to take over "-2".

And there is currently no way to continue cherry-picking or
reverting if there is a problem with one commit. It's also
not possible to abort the whole process. Some future work
should provide the --continue and --abort options to do
just that.
