[PATCH v3 27/38] sequencer (rebase -i): respect strategy/strategy_opts settings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The sequencer already has an idea about using different merge
strategies. We just piggy-back on top of that, using rebase -i's
own settings, when running the sequencer in interactive rebase mode.
