Describe the bug
When a command's flags have their Value set, app help <subcommand> doesn't show those default values, while app <subcommand> --help works correctly.
To reproduce
- Create a command with flags that have default values.
- Use
app help <command>to produce a help output.
Observed behavior
app help <command> shows zero values for the flags.
Expected behavior
app help <command> must show the default values set for those flags.
Additional context
I have created a sample program on Go playground.
These are the outputs that I get when generating help:
$ go run . help greet
NAME:
hello greet - Greets you with your age
USAGE:
hello greet [command options] [arguments...]
OPTIONS:
--name value
--age value (default: 0)
--help, -h show help
$ go run . greet -h
NAME:
hello greet - Greets you with your age
USAGE:
hello greet [command options] [arguments...]
OPTIONS:
--name value (default: "Foo")
--age value (default: 40)
--help, -h show help
