Update output for help text formatting to not use '='

[s2k]

🌈 (Not a pull request, but still)

Current Behaviour

Thor apps, such as rails display options that come with an argument with an equals sign.
In the example below, that's [--ruby=PATH]

> rails help new
Usage:
  rails new APP_PATH [options]

Options:
…
  -r, [--ruby=PATH]               # Path to the Ruby binary of your choice

Suggested Change

Use a space instead of the '=' in the help output, like this

  -r, [--ruby PATH]               # Path to the Ruby binary of your choice

Rationale

It seems to be common practice to not use the '=' sign, neither in practical usage, nor documentation.

Examples:

• The "Agile Web Development with Rails" books (the beta for Rails 7, in particular)
• @dhh on Twitter ➙ https://twitter.com/dhh/status/1472002099684659202
• The Rails team in the announcement of Rails 7 at https://rubyonrails.org/2021/12/15/Rails-7-fulfilling-a-vision
• The tailwindcss-rails documentation at https://github.com/rails/tailwindcss-rails#installation

Note

I'd be happy to work on & provide a corresponding PR, should I get the specs to pass.

I think it depends on the tool. This Stackoverflow, for example, indicates that both styles are used in various contexts: https://unix.stackexchange.com/questions/573377/do-command-line-options-take-an-equals-sign-between-option-name-and-value

I think this would be a nice addition but I think it should be configurable per command. Do you still want to work on it?
