In the split case,
B o
|
B o B o o A2 A2 o
| -> | | -> |
A o A x o A1 A1 o
| |/ |
Z o Z o Z o
Rebase calls delayedstrip([B], 'rebase'), and strip calls delayedstrip([A],
'split'). It seems better to put them in a single backup file since B
depends on A. That could reduce bundle size, and the user seems to always
want to restore B and A together.
It seems the only difference we care about is whether the node to strip is
intermediate or not. I guess we could figure that out automatically from a
transaction, or a snapshot of all changelog heads for multiple transaction
case.
