I had imagined a "not" token at the front of the refspec, like:

  git fetch origin +refs/heads/*:refs/remotes/origin/* ^refs/heads/foo

In this case, a colon in the refspec would be an error. An alternative would be:

  git fetch origin +refs/heads/*:refs/remotes/origin/* refs/heads/foo:

I.e., to say "put foo to nowhere". But generally refspecs do not affect each other. So "refs/heads/foo:refs/heads/bar" would generally work _in addition_ to the other refspec. Making the "null destination" work differently might be confusing.

I dunno. I have not thought very hard on the topic, so maybe there are some subtle cases I am missing.
