+When <refspec> stores the fetched result in tracking branches,
+the tags that point at these branches are automatically
+followed.  This is done by first fetching from the remote using
+the given <refspec>s, and if the repository has objects that are
+pointed by remote tags that it does not yet have, then fetch
+those missing tags.  If the other end has tags that point at
+branches you are not interested in, you will not get them.
