This improves the analogy with "git rebase" (in olden days --continue was the way to preserve authorship when a rebase encountered conflicts) and fits well with a general UI goal of making "git cmd --continue" save humans the trouble of deciding what to do next. Example: after encountering a conflict from running "git cherry-pick foo bar baz": CONFLICT (content): Merge conflict in main.c error: could not apply f78a8d98c... bar! hint: after resolving the conflicts, mark the corrected paths hint: with 'git add ' or 'git rm ' hint: and commit the result with 'git commit' We edit main.c to resolve the conflict, mark it acceptable with "git add main.c", and can run "cherry-pick --continue" to resume the sequence. $ git cherry-pick --continue [editor opens to confirm commit message] [master 78c8a8c98] bar! 1 files changed, 1 insertions(+), 1
