flyctl doesn't reject extra bogus args after "ips list".

Paste your fly.toml

primary_region="sea"

Command output:

$ fly ips ls -a tb
VERSION IP      TYPE    REGION  CREATED AT 

$ fly ips ls -a tb sdlkfjsdlkfjsdlkfjslkdfj
VERSION IP      TYPE    REGION  CREATED AT 

$ echo $?
0

What would be the expected result for you? For my own application, it works as I would expect it to in that anything after the -a | --app flag is disregarded:

$ flyctl ips ls -a gobarchar
VERSION IP                      TYPE                    REGION  CREATED AT
