I'm pretty sure we use STATUS_FORMAT_LONG elsewhere as a synonym for
"the user has not set anything".
Ah, here it is:
$ git grep -nA1 '== STATUS_FORMAT_LONG'
1073: if (s->null_termination && status_format == STATUS_FORMAT_LONG)
1074- status_format = STATUS_FORMAT_PORCELAIN;
--
1201: if (s.null_termination && status_format == STATUS_FORMAT_LONG)
1202- status_format = STATUS_FORMAT_PORCELAIN;
I think you would want something like this. I had originally intended to
make it a refactoring patch that would come before yours, but some of
the cleanups are tied to actually adding --long. So I think you would
want to squash it together with your patch and combine the commit
messages.

Subject: [PATCH] status: refactor output format to represent "default"
When deciding which output format to use, we default an
internal enum to STATUS_FORMAT_LONG and modify it if
"--porcelain" or "--short" is given. If this enum is set to
LONG, then we know the user has not specified any format,
and we can kick in default behaviors. This works because
there is no "--long" which they could use to explicitly
specify LONG.
Let's expand the enum to have an explicit STATUS_FORMAT_NONE,
in preparation for adding "--long". Then we can distinguish
between LONG and NONE when setting other defaults. There are
two such cases:
1. The user has asked for NUL termination. With NONE, we
currently default to turning on the porcelain mode.
With an explicit --long, we would in theory use NUL
termination with the long mode, but it does not support
it. So we can just complain and die.
2. When an output format is given to "git commit", we
default to "--dry-run". This behavior would now kick in
when "--long" is given, too.
