git-am: make --abort less dangerous

Browse Source 
When you are in the middle of "git rebase", "git am --abort" by mistake
would have referred to nonexistent ORIG_HEAD and barfed, or worse yet, used
a stale ORIG_HEAD and taken you to an unexpected commit.

Also the option parsing did not reject "git am --abort --skip".
