Wrapping --help output lines to 80 (or whatever) characters

[farnasirim]

      --smtp-server-host string   SMTP server host address to use for sending emails. Default: smtp.gmail.com                                                            
      --smtp-to string            Address to send the diff email to. Defaults to smtp-user

I had a look around the code and figured that this is not supported. Was wondering if you would accept a patch.

This is not very trivial to do right now as the padding that comes before the command descriptions is dependent on the longest flag name + type and calculating the padding and repadding subsequent lines is cumbersome for the user.

Therefore I think it makes more sense to handle this inside cobra.

Having worked on a few different tools I agree that the general text-wrapping problem is frustrating for every dev to handle and if cobra could do it for the help/usage it would make a lot of sense.

The main issue is that there are lots of different approaches/libraries that help so it may be a bit opinionated. Open to a PR for sure though.
