Describe the bug

Relates #8423

In the latest release 2.44.0, the behavior of gh pr create has changed in a way that breaks my most common workflow. What I want to do is this: create a PR with sensible defaults for title and body (based on the commits) and edit the body before submitting it. This was the old default behavior, and when the branch only contained one commit, the PR title would be the commit headline. Now the default PR title is the branch name, which is rarely as descriptive.

I appreciate the --fill-verbose and --fill-first options, and would use them, but using any of the --fill* options leads to the PR being created straight away with no ability to edit the body.

$ gh --version
gh version 2.44.0 (2024-02-12)
https://github.com/cli/cli/releases/tag/v2.44.0

Steps to reproduce the behavior

1. Have a branch with a single commit
2. gh pr create or gh pr create --fill-first

Expected vs actual behavior

Expected behavior:

• The PR title is set to the commit headline
• We can edit the body locally before creating the PR

OR

• We can use --fill-first or --fill-verbose to influence how the title and body are set
• We can edit the body locally before creating the PR

Actual:

• If no --fill* option is provided, the PR title defaults to the branch name
• If a --fill* option is provided, there is no ability to edit the body, the PR is created instantly.
