Option parsing of docker ps command is incorrect with concatenated option flags

[krishnakumarg1984]

If we pass more option flags to the docker ps command in the concatenated short-form style, e.g. docker ps -aq where the -q flag is concatenated with the -a flag to result in the combined -aq flag, we do not get the correct output from dops.

As an example, if we have the following situation

$ docker ps -a
CONTAINER ID   IMAGE     COMMAND                  CREATED         STATUS                     PORTS     NAMES
030aa141e0bc   nginx     "/docker-entrypoint.…"   4 minutes ago   Exited (0) 3 minutes ago             website

dops -a works absolutely fine.

$ dops -a
CONTAINER ID    NAME       IMAGE    TAG    CREATED AT (+01:00 BST)    STATE       STATUS                      PUBLISHED PORTS
------------    -------    -----    ---    -----------------------    --------    ------------------------    ---------------
030aa141e0bc    website    nginx           2023-05-18 16:00:36        [EXITED]    Exited (0) 4 minutes ago

while, the -aq combined flag does not produce the correct output. With docker ps -aq, we get the container ID as expected i.e. 030aa141e0bc.

However, dops -aq produces an empty output. The long form, dops -a -q does work correctly though. The bash/zsh/fish alias functions are also correspondingly broken.

Yeah, I guess the commandline parser currently does not pick up the short syntax - I'll try to look into it next week
