Re: [PATCH 4/7] merge,tag: describe -m just like commit

Well, any option is effective only in the case when the command succeeds
- "commit -m msg" specifies only a message when a commit is created at
all, etc. So, it usually is a trivial remark. It is slightly different
for merge because merge may succeed by doing a fast-forward without
creating a merge commit, which is why I wrote "merge commit message".
So, the parenthetical remark would have to be "if a non-ff merge commit
is created". I'm afraid "merge created" alone would not convey this.

Ok.  Thanks for clarifying the thinking behind it.
