Of course, when you drop a commit, you'll -always end up dropping all the commits that depended on it, and if you -actually got somebody else to pull that commit you can't drop it from -_their_ repository, but undoing things is not impossible. - -For example, let's say that you've made a mess of things: you've committed -three commits "old->a->b->c", and you notice that "a" was broken, but you -want to save "b" and "c".
