in the just released ngit v1.1.1 `send` doesn't assume the commits to include in the proposal but presents a multi-select, defaulting to the likely commits.
These likely commits now now taken from a comparison of the current branch with 'origin/master' or 'origin/main' falling back to 'master' or 'main'.
Thanks for discovering this commit selection issue to help iron our some of the hard edges in ngit.
