messages confusing

Hi all,

I had those messages today

  % git merge origin/master
    Already uptodate!
    Merge made by recursive.
  %

with git version 1.7.2.rc1.210.g7b476 and I wonder if it is really
intended.  It did create an empty merge commit but I find both messages
together a bit confusing here.  Why would Git merge if uptodate?

I don't think I will have time to investigate in the comming weeks but
you should be able to reproduce it by following these steps (it is by
now, at least):

  % git clone git://github.com/nvie/gitflow.git
  % cd gitflow
  % git merge origin/master
  %

Thanks,
