This error didn't do a great job at formatting. If a StatusError was
produced without a Status message, it would print a very non-informative
error, with information missing.
Let's update the output:
- If a status-message is provided; print just that (after all the
status code is something that can be found from the shell, e.g.
through `echo $?` in Bash).
- If no status-message is provided: print a message more similar to
Go's `exec.ExecError`, which uses `os.rocessState.String()` (see [1]).
Before this patch, an error without custom status would print:
Status: , Code: 2
After this patch:
exit status 2
In situations where a custom error-message is provided, the error-message
is print as-is, whereas before this patch, the message got combined with
the `Status:` and `Code:`, which resulted in some odd output.
Before this patch:
docker volume --no-such-flag
Status: unknown flag: --no-such-flag
See 'docker volume --help'.
Usage: docker volume COMMAND
Manage volumes
Commands:
create Create a volume
inspect Display detailed information on one or more volumes
ls List volumes
prune Remove unused local volumes
rm Remove one or more volumes
update Update a volume (cluster volumes only)
Run 'docker volume COMMAND --help' for more information on a command.

With this patch, the error is shown as-is;
docker volume --no-such-flag
unknown flag: --no-such-flag
See 'docker volume --help'.
Usage: docker volume COMMAND
Manage volumes
Commands:
create Create a volume

While the exit-code is no longer printed, it's still properly handled;
echo $?
