[PATCH 2/5] sequencer: remove CHERRY_PICK_HEAD with sequencer state

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

 



Make remove_sequencer_state() remove '.git/CHERRY_PICK_HEAD' when
invoked aggressively, since we want to treat it as part of the
sequencer state now.  While at it, make some minor improvements to the
function.
