show flag alias on the help page

[NikoKS]

Hi, since the feature to use flags alias has been added. Is there a way to show the alias on the help page?
e.g. something like this:

FLAGS
--flag, -f=FLAG
This is a description of the flag: flag

If not implemented yet, do you have a plan to implement this?

can I work on this issue?

#318 addresses this (and duplicate #317), but I have not yet reviewed it.
One way you can help out would be to review #318, looking for any potential issues with it.
