[New-bugs-announce] [issue26503] argparse with required field , not having new line separator in -help dispaly

[Mohankumar]

New submission from Mohankumar:

We are using Python argsparse library here to display below --help message .
In --help option , new line option not handled correctly , Especially in "mandatory parameters" (required=True) better to place a new line before for better readability , Since it not having any separators like list brackets in "Non Mandatory parameters".

For example In below help , there must be a new line before "--protocol" and " --action" for better readability


Neutron firewall-rule-create [-h]
                                    [-f {html,json,json,shell,table,value,yaml,yaml}]
                                    [-c COLUMN] [--max-width <integer>]
                                    [--noindent] [--prefix PREFIX]
                                    [--request-format {json,xml}]
                                    [--tenant-id TENANT_ID] [--name NAME]
                                    [--description DESCRIPTION] [--shared]
                                    [--source-ip-address SOURCE_IP_ADDRESS]
                                    [--destination-ip-address DESTINATION_IP_ADDRESS]
                                    [--source-port SOURCE_PORT]
                                    [--destination-port DESTINATION_PORT]
                                    [--enabled {True,False}] --protocol
                                    {tcp,udp,icmp,any} --action
                                    {allow,deny,reject}
