This isn't strictly related to your patch, but since the rationale here
describes the concept of a background job and people might end up using
it as a reference, do you want to add in --no-tags to help them out?

That's a good idea. I keep forgetting about that. It's interesting that
tags are fetched even though my refpsec does not include refs/tags.

Yeah, because tag-following is an extra thing outside of the refspecs. I
think it would be nice if there were a way to specify a "following"
refspec, something like:

  ~refs/tags/*:refs/tags/*

(where "~" is just a character I picked out of the blue that I think
doesn't have any other meaning there now). And then we could specify it
in the config alongside other refspecs, override it with a refmap, etc.

As a bonus, it would also give us a stepping stone towards being able to
do remote-specific tags like:

  [remote "origin"]
  url = ...
  fetch = +refs/heads/*:refs/remotes/origin/heads/*
  fetch = ~refs/tags/*:refs/remotes/origin/tags/*

But I'm sure there are a lot of backwards-compatibility gotchas.
