support comma-separated fetch specs list?

It's nice to have negative ref spec support with 2.29 release, so now
we can have

[remote "origin"]
  fetch = +refs/heads/*:refs/remotes/origin/*
  fetch = ^refs/heads/gh-pages

What about having all the fetch specs put together in one comma-separated list?
Like this:

[remote "origin"]
  fetch = +refs/heads/*:refs/remotes/origin/*,^refs/heads/gh-pages

Thanks
