strip: move attributes shortcut assigned earlier This series will add support for "soft" stripping using the archived phase in addition to the usual heavy weight revlog stripping. First, we need to refactor the strip function to extract logic common to the "soft-strip" case. We are about to extract bits of the strip function into separate functions. Those blocks of code contain variables for frequently accessed attributes. We move those variables outside of the soon to be moved blocks.
