"git cherry-pick", upon seeing a conflict, says: hint: after resolving the conflicts, mark the corrected paths hint: with 'git add <paths>' or 'git rm <paths>' hint: and commit the result with 'git commit' as if running "git commit" to conclude the resolution of this single step were the end of the story. This stems from the fact that the command originally was to pick a single commit and not a range of commits, and the message was written back then and has not been adjusted. When picking a range of commits and the command stops with a conflict in the middle of the range, however, after resolving the conflict and (optionally) recording the result with "git commit", the user has to run "git cherry-pick --continue" to have the rest of the range dealt with, "--skip" to drop the current commit, or "--abort" to discard the series. Suggest use of "git cherry-pick --continue/--skip/--abort" so that the message also covers the case where a range of commits are being picked. Similarly, this optimization can be applied to git revert, suggest use of "git revert --continue/--skip/--abort" so that the message also covers the case where a range of commits are being reverted. It is worth mentioning that now we use advice() to print the content of GIT_CHERRY_PICK_HELP in print_advice(), each line of output will start with "hint: ".
