I really don't think it's a good idea to start making a merge commit
without confirming that that's what the user wants. Elijah and Robert
seemed to agree. However, we can start by just putting in a friendly
educational message and then continue the discussion about whether or
not to make a future version of Git abort upon printing the warning.

I'll send a new version that has a longer and more clear warning message.
