cp: makes --preserve requires =

prevents --preserve to eat the next argument when no value is passed. default value for --preserve is set to mode,ownership,timestamps before the patch: cp --preserve foo bar error: invalid value 'foo' for '--preserve [<ATTR_LIST>...]' [possible values: mode, ownership, timestamps, context, link, links, xattr, all] Signed-off-by: Guillaume Ranquet <[email protected]>
