It is true that "checkout" does funny things to special case the
remote-tracking branches, like setting up the branch.<name>.merge
configuration or even inferring the name of the local branch to be
created.  

But I have to say that this one, especially the configuration
variable, goes way too far.  The usual uses of remote-tracking
branch names, e.g.,

    git log -1 origin/master
    git grep frotz origin/master
    git rev-list --count origin/maint..origin/master

to name a specific object all assume and rely on the stability of
them.  Should the configuration cause a fetch to happen before any
of these uses of remote-tracking branches for consistency?
