Hi, Jani.  I appreciate you've put a lot of work into this series, but
I'll be the same devil's advocate that I was to David previously.  Why
do we need a command line option here when we already have an
environment variable that handles just this?  Is there some benefit to
having a command line option for this that I don't see?  I see this as
another instance of an option that regular users will rarely use, if
ever.

In general, I am a strong advocate of keeping the CLI slim.  IMHO,
adding more options makes the interface clunkier, and the manual harder
to parse, and I'm against adding things that a normal user would likely
never use.  In retrospect, I should have had the same objection to the
--format-version option, which I think could have just been an env var
as well.

jamie.
