revset: id() called with 40-byte strings should give the same results as for short strings The patch solves two issues: 1. id(unknown_full_hash) aborts, but id(unknown_short_hash) doesn't 2. id(40byte_tag_or_bookmark) returns tagged/bookmarked revision, but id(non-40byte_tag_or_bookmark) doesn't After the patch: 1. id(unknown_full_hash) doesn't abort 2. id(40byte_tag_or_bookmark) returns empty set
