[New-bugs-announce] [issue45275] Make argparse print description of subcommand when invoke help doc on subcommand

[Chuanlong Du]

New submission from Chuanlong Du <longendu at gmail.com>:

I have command-line script `blog` written using argparse. It supports subcommands. When I check the help doc of a subcommand, e.g., using `blog convert -h`, it prints the help doc of the subcommand `blog convert` but doesn't print the description of the subcommand `blog convert`. A screenshot is attached. It is quite often that I know a command-line application have certain subcommands but I forget exactly what they do. It would be very helpful if `blog subcmd -h` prints the description of the subcmd so that users do not have to call `blog -h` again to check exactly what the subcommand does.
