New submission from Stefan Seefeld <ste...@seefeld.name>:
I'm using Python's `argparse` module to define optional arguments.
I'm calling the `argparse.add_argument` method to add both short and long
arguments, but I notice that the generated help message lists some information
twice. For example:
```
argparse.add_argument('-s', '--service',...)
```
will generate
```
-s SERVICE, --service SERVICE
```
and when I add a `choices` argument, even the choices list is repeated. I think
it would be more useful to suppress the repetition to produce output such as
```
-s|--service SERVICE ...
```
instead with both the meta var as well as choices etc. printed only once.
