Absent this fix, attempts to rebase an orphan branch using "rebase -m"
fails with:
$ git rebase -m ORPHAN_TARGET_BASE
First, rewinding head to replay your work on top of it...
fatal: Could not parse object 'ORPHAN_ROOT_SHA^'
Unknown exit code (128) from command: git-merge-recursive ORPHAN_ROOT_SHA^ -- HEAD ORPHAN_ROOT_SHA
To fix, this will only include the rebase root's parent as a base if it exists,
so that in cases of rebasing an orphan branch, it is a simple two-way merge.
Note the default rebase behavior does not fail:
$ git rebase ORPHAN_TARGET_BASE
First, rewinding head to replay your work on top of it...
Applying: ORPHAN_ROOT_COMMIT_MSG
Using index info to reconstruct a base tree...
A few tests were expecting the old behaviour to forbid rebasing such
a history with "rebase -m", which now need to expect them to succeed.
