...plus a few others. And fixes to actual parsing. If a command's usage message includes '...' in the argument list, assume it can take unlimited arguments. Nothing we can check. For all others, though, the ALL-CAPS part on the right-hand side of the usage message will define an upper bound on the number of arguments accepted by the command. So in our 'podman --help' test, generate N+1 args and run that command. We expect a 125 exit status and a suitably helpful error message. Not all podman commands or subcommands were checking, so I fixed that. And, fixed some broken usage messages (all-caps FLAGS, and '[flags]' at the end of 'ARGS'). Add new checks to the help test to prevent those in the future. Plus a little refactoring/cleanup where necessary. Signed-off-by: Ed Santiago <santiago@redhat.com>
