As "object_name" is now allowed to be any name in the 'extended
SHA-1' syntax (cf. Documentation/revisions.txt), you should be a bit
more careful in quoting.

	oid=$(git rev-parse --verify "$object_name")

Likewise.  You may not currently use a path with SP in it to name a
tree object, e.g., "HEAD:Read Me.txt", but protecting against such a
pathname is a cheap investment for futureproofing.

Looking good otherwise.  Thanks.
