When i run gpg --quiet --quick-sign-key, it emits the following to stdout:
sec rsa3072/3E0FD8A37C52EA70
created: 2019-07-01 expires: 2021-06-30 usage: SC
trust: ultimate validity: ultimate
Primary key fingerprint: 8D03 385D 14B9 CA0F B627 A47C 3E0F D8A3 7C52 EA70
test key
This key is due to expire on 2021-06-30.If i use --with-colons, it is even worse: a mix of colon-delimited and non-colon-delimited output:

Note that there is also an additional line of whitespace at the top and bottom too.
