AFAIK, Git should only auto-follow tags that are reachable from the branches you fetch (in this case master). Are you saying that you get tags pointing to other history that is NOT reachable from the master branch? (i.e. are you getting tags for which "git merge-base $tag master" is not equal to "git rev-parse $tag")? Re-reading the man page, I do see the following: "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." This can be interpreted as saying that even unreachable objects in your local repo that are pointed to by some remote tag will cause that tag to be fetched, and in effect resuscitate the previously-unreachable object. If this is indeed how it works, I would be tempted to label this a bug in the auto-following behavior, as it's probably not what most people would expect. In that case, yes, you should be able to get your desired behavior by first purging all unreachable objects. Something like "git gc --prune=now" should do the job.
