tests: demonstrate how continuing rebase after upgrade can result in merge
If the user starts a rebase with an hg version before
9c9cfecd4600
(rebase: don't use rebased node as dirstate p2 (BC), 2020-01-10) and
then runs into conflicts, they will be dropped out to the shell with
the rebased node set as the dirstate's second parent. If they then
upgrade to a later hg version, it will respect the dirstate's parents
and will create a merge commit even if the user was rebasing a
non-merge commit.
