True as you mean it. However, it is technically possible (especially in git) to change *pointers* to shared history in a way that can really confuse the tool. And in Bazaar and Mercurial it's even worse; they don't provide reflogs or rerere, so you can really wedge things if the rebase involves conflicts and the original branches have been deleted. > So the warning is pretty much spurious. I disagree, strongly. It's one of those things where most people most of the time will quickly learn to do things safely, but it will save a few people a lot of trouble.
