[New-bugs-announce] [issue13818] argparse: -h listening required options under optional arguments

[Miguel Godinho]

New submission from Miguel Godinho <m at miguelgodinho.com>:

Adding a 'required optional argument' as with:
```
app.add_argument('--dbsnp', required=True)
```

will still result on having that argument listed under the optional when the app is called with the help option (-h)

Please note that the usage line is rendered ok (no square brackets around the 'required optional argument').
