The option '-k' says that the given commit and _all_ of its ancestors are kept as-is. However, if a to-be-rewritten commit branched from an ancestor of an ancestor of a commit given with '-k', filter-branch would fail. Example: A - B \ C If filter-branch was called with '-k B -s C', it would actually keep B (and A as its parent), but would rewrite C, and its parent. Noticed by Johannes Sixt.
