Deprecated help message

Hi,

It seems I hit a deprecated help message:

% git pull
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream nsiv2 origin/<branch>

% git branch --set-upstream nsiv2 origin/nsiv2
The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to
Branch nsiv2 set up to track remote branch nsiv2 from origin.

Jeroen.
