[New-bugs-announce] [issue27303] [argparse] Unify options in help output

[Memeplex]

New submission from Memeplex:

Currently when you specify more than one name for an option (typically short and long versions) each name is listed with its entire arg list. This is annoying for options taking many args or choices, for example:
 
  --type {html,pdf,github,blogger}, -t {html,pdf,github,blogger}

Wouldn't it be better to just show something like:

  --type|-t {html,pdf,github,blogger}
