When a new branch is created it has no push settings:
git checkout -b ahead_of_main_status__tmp2
git push
fatal: The current branch ahead_of_main_status__tmp2 has no upstream branch.
To push the current branch and set the remote as upstream, use
git push --set-upstream origin ahead_of_main_status__tmp2
To have this happen automatically for branches without a tracking
upstream, see 'push.autoSetupRemote' in 'git help config'.
Once the users runs that suggested command
git push --set-upstream origin ahead_of_main_status__tmp2
then the 'branch.<name>.merge' and 'branch.<name>.remote' no longer hold the reference to "upstream/HEAD".
For sure, it would be great to re-use previous logic for this, but can it really be done without new logic?
