We want to teach the function to also handle blobs and trees to get their raw data, without parsing a blob (whose contents looks like a commit or a tag) incorrectly as a commit or a tag. Skip the block of code that is specific to handling commits and tags early when the given object is of a wrong type to help later addition to handle other types of objects in this function.
