Here for your amusement is a way to get around this problem:

if [ "`git pull`" == "`git pull`" ]
then
        echo Up to date
else
        make update
fi

You pay double the cost every time you use it but if they ever *do*
change the message, it's not going to break. But of course, if the shell
ever optimizes the second git pull away, you are back at square one...
