Setting up dw-free and dw-nonfree

[kaberett]

The instructions on setting up dw-nonfree (and possibly in other places) use the --set-upstream flag. Using those instructions gives the message:

The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to

Someone more familiar with git tell me what I should be editing those instructions to so's not to break anything? Cheers!
