The last patch just documents the status quo, which is not a bug per se.
Therefore, no failure, but change in the definition of "success".

My reasoning is twofold:

- consistency between "git show commit" and "git show blob"

- "git show" is a user facing command, and as such should produce output
consumable by humans; whereas "git cat-file" is plumbing and should
produce raw data unless told otherwise (-p, --textconv).
