cherry-pick: handle "-" after parsing options

Currently, we only try converting argv[1] from "-" into "@{-1}".  This
means we do not notice "-" when used together with an option.  Worse,
when "git cherry-pick" is run with no options, we segfault.  Fix this
by doing the substitution after we have checked that there is
something in argv to cherry-pick and know any remaining options are
meant for the revision-listing machinery.

This still does not handle "-" after the first non-cherry-pick option.
For example,

	git cherry-pick foo~2 - bar~5

and

	git cherry-pick --no-merges -

will still dump usage.
