CTAS command tags

I was recently surprised by the following inconsistencies in returned
command tags for CTAS:


postgres=# create table a as select 123;
SELECT 1

postgres=# create table b as select 123 with data;
SELECT 1

postgres=# create table c as select 123 with no data;
CREATE TABLE AS


Shouldn't we make the first two tags (which are likely the same code
path; I haven't looked) the same as the third?  I can look into writing
the patch if desired.
