git am or rebase advise the user to use `git (am | rebase) --skip` to
skip the commit. cherry-pick and revert also have this concept of
skipping commits but they advise the user to use `git reset` (or in
case of a patch which had conflicts, `git reset --merge`) which on the
user's part is annoying and sometimes confusing. Add a `--skip` option
to make these commands more consistent.
In the next commit, we will change the advice messages hence finishing
the process of teaching revert and cherry-pick "how to skip commits".
