Describe the bug

Submitting a PR for an unforked repo hangs without any feedback to the user, while it figures out the forking stuff in the background.

gh version 1.1.0 (2020-10-06)

Steps to reproduce the behavior

1. Click the code clone button on a third-party repo and copy the GH CLI command for cloning
2. Paste that command in terminal
3. Make changes
4. Commit
5. gh pr create
6. When asked where to push the master branch, just hit at the "create a fork..." suggestion
7. Fill in the PR form in the terminal
8. Submit

Expected vs actual behavior

Actual

For several minutes, there are no updates at all in the terminal. It looks dead. After...maybe 5 minutes, maybe longer? ... it dumps out the rest of the output (see below) including that fatal: Could not read from remote repository but then says it successfully created the PR.

I checked in the browser, and it turns out it completed successfully.

Expected

1. Spitting out that "fatal error" shouldn't happen when it's working just fine. That's confusing. Maybe hold it and spit it out later if things actually don't end up working out?
2. Ideally, no long wait.
3. If there has to be long wait, then a progress bar or spinner would be good at the bare minimum. It would be better if it kept the user in the loop on what's going on. For example:

Creating fork {spinner}
Pushing code to fork {spinner}
Creating pull request {spinner}
Done!

(Sure, continue to include the full verbose git output like in the log, but you clearly know how to make bold text in the terminal, so little headings would be nice.)
