This is has been requested various times on StackOverflow, and possibly here (I'd have to do a search).

The closest thing to making a compact action_invocation is to set the metavar to '', and even thing we get a space, eg.

     -f , --foo   Help text

This repeat has been a part of argparse from the beginning, so I can't see changing the default behavior.  But we could add a HelpFormatter subclass that changes one (or two methods) such as _format_action_invocation.  Subclassing the formatter is the accepted way of adding help features.   I, and possibly others, must have suggested such a change on SO.

Of course people can use such a subclass without it being part of the standard module.
