test_description='Exercise pushing patches applied upstream.

Especially, consider the case of a patch that adds a file, while a
subsequent one modifies it, so we have to use --merged for push to
detect the merge.  Reproduce the common workflow where one does not
specify --merged, then rollback and retry with the correct flag.'
