Add a command line switch to git-rebase to allow a user the ability to specify that they want to keep any commits in a series that are empty. When git-rebase's type is am, then this option will automatically keep any commit that has a tree object identical to its parent. This patch changes the default behavior of interactive rebases as well. With this patch, git-rebase -i will produce a revision set passed to git-revision-editor, in which empty commits are commented out. Empty commits may be kept manually by uncommenting them. If the new --keep-empty option is used in an interactive rebase the empty commits will automatically all be uncommented in the editor.
