I tested your patch; the two methods aren't identical. In fact, yours
fixes a bug. :)

In t4202, we have a branch name and a tag name that are the same
(octopus-a), and we "git merge octopus-a". This actually merges the tag,
but because the branch name existed, we write "Merge branch 'octopus-a'"
in the log, which is not true. With your patch, it does the right thing
and says "Merge commit 'octopus-a'".

The simple thing is to just update the "expect" text. Though the current
behavior does show off the ability to collape the two branches and say

  Merge branches 'octopus-a' and 'octopus-b'

instead of

  Merge commit 'octopus-a'; commit 'octopus-b'

which we could preserve that by renaming the tags, as below.
