histedit: add a hint about enabled dropmissing to histedit edit comment Adds a hint to histedit comment reminding user about enabled dropmissing. This will make the enabled dropmissing more visible. The example comment: # Edit history between b592564a803c and b54649a8a63f # # Commits are listed from least to most recent # # You can reorder changesets by reordering the lines # # Commands: # # e, edit = use commit, but stop for amending # m, mess = edit commit message without changing commit content # p, pick = use commit # b, base = checkout changeset and apply further changesets from there # d, drop = remove commit from history # f, fold = use commit, but combine it with the one above # r, roll = like fold, but discard this commit's description # # Deleting a changeset from the list will DISCARD it from the edited history!
