"Undo" is a better name than "revert" because: - "revert" sounds like it has something to do with `git-revert` but they are entirely different; - "undo" is consistent with vim's "undo": discarding changes and going back to the original. Maintain backwards compatibility and add deprecation warnings. Closes #306.
