Subject: cli: implement structured output version 4
X-Git-Tag: 0.25_rc0~41

cli: implement structured output version 4

Since the error field is unused by the emacs front end, no changes are
needed other than bumping the format version number.

As it is, this is a bit overengineered, but it will reduce duplication
when we support gmime 3.0
