Re: [PATCH] merge: allow "-" as a short-hand for "previous branch"

I agree this is is useful, but is there a danger of this being a
common typo, and people merging in previous branches a lot more often

as fatal, but if I ever mistype "git merge -" -- I'm now left with an
unraveling exercise to do.

Just like you can checkout the previous branch back if you found you
checked out a wrong branch by a typo, if you found that you merged a wrong
branch, you can just reset it away back to ORIG_HEAD, no?

Or am I missing something more obvious?
