Hmmm, maybe, without knowing it. Originally, that section of the .git/config file had "*"'s where "home" was. To clarify, the original was:

[remote "origin"]
	url = <some_ip_address>:git.repos/environ.git
	fetch = +refs/heads/*:refs/remotes/origin/*

and the current one is now:

[remote "origin"]
	url = <some_ip_address>:git.repos/environ.git
	fetch = +refs/heads/home:refs/remotes/origin/home

Maybe I had made that change and this is the first time I am doing a fetch to using that change. I thinking that was the cause of this, because I retried doing a fetch into a separate throw-away repo with just the change of IP address, and it did not need to fetch anything more. I had not executed git-filter-branch at all.

Good, that is what I would have expected.
