These are better instructions than mine, but you should insert a rebase
before the git stash pop. It also assumes that master is tracking the
w3c master rather than the user's own fork. I think something like the
following might work generically:

export UPSTREAM=$(git remote --verbose | grep w3c/web-platform-tests |
head -n1 | cut -f1)

git checkout master
git fetch $UPSTREAM
git merge --ff-only $UPSTREAM/master #If you have commits on master this
will fail, but that's OK
git submodule update --recursive
git checkout @{-1}
git rebase $UPSTREAM/master
git stash pop
