Well, in worst case, why not have something like --follow-dirs, then?

The case at hand is that we unfortunately named a directory based on the
codename of some software for the time.

Now, we have improved that software and the codename is different
accordingly. Now, instead of "pastcodename", I would change the directory
name to "src" to be future proof, but here, I face these difficulties:

1) The directory name is stuck with some ancient codename and it therefore
will be confusing for the rest of the life cycle for this project.

2) We get unfollowable directories. At best, we could use some scripts to
work this around, but why not address this directly in git?

I think renaming a directory without losing the history would be really cool
to have, one way or another. If that requires a separate option, I am happy
with that, but what I would really like to avoid is not being able to rename
directories without losing the history.

Note that I am speaking from user point of view. I do not know the
nitty-gritty technical details, but that is just implementation details as
far as I am concerned, anyway.
