These docs are really confusing, but it is working as intended, and
really should be re-documented.
The `git remote prune` subcommand just ends up piggy-backing on
git-fetch, whose behavior is explained here:
https://git-scm.com/docs/git-fetch.html#git-fetch---prune
It's worked this way since at least v1.8.5.6, maybe at some distant
point in the past it only did this for branches when invoked via
git-remote as the documentation says.
RELATED:
I've actually had the reverse problem with this. I want some way to turn
this behavior on without explicitly hacking the refspec, so I can do it
globally in /etc/gitconfig or in ~/.gitconfig without screwing with the
config of each checkout on certain machines.
You can set fetch.prune=true, but that only prunes the branches, you
need to inject remote.origin.fetch into each checkout, unless I've
missed some way of doing this.
I wanted to add fetch.pruneTags that would make it as if you had
refs/tags/*:refs/tags/* in the fetch spec, but I haven't hacked that up
yet, if anyone can see any inherent issue with that plan I'd like to
know about it.
