I'm using this new type to handle the "index" line of a git patch file, where object ids are generally shorter than 40 characters and thus aren't parsable by ObjectId. Reading the short id is important because we can validate that a patch applies correctly by computing the SHA-1 of the result and testing it against the abbreviated id read in the "index" line. If the base object SHA-1 matches the abbreviated line then the result of applying the patch must also match; if it doesn't the patch application logic is broken. Shawn O.
