I realize that "may be updated" is strictly correct, in that if the remote's
branches have not changed since the last fetch then the local tracking
branches won't change.
But it took me a second or two to think of that. The "may" kindof tripped me
up. The fact is that the local tracking branches are always updated to match
the remote's branches, it's just that sometimes the remote's branches don't
change. So I think it would be clearer to say
the remote-tracking branches are updated
because this makes it clear that the command always makes your local tracking
branches match the remote's.
