Ob thunk pack <src> complains about merge issue

[augyg]

From running ob thunk pack src -v the command fails with:

This can be resolved by git push -u origin but for some reason it doesn't tell me this, even though I've seen messages in previous pack commands to run this git push command.

Based on git push -u fixing this, there is no actual merge issue IIUC
