Pull request #1162 (2020-07-12 15:38:05)

Handle linebreaks in custom completions.
If a command/flag description contains a linebreak than the shell completion script will interpret this as new command/flag.

To fix this we should only use the first line from the description in the output.

e.g. `cmd.Flags().String("flag", "", "Description for flag\nlonger description")`

Luap99: @marckhouzam Please take a look.
I noticed this while testing #1146 because this also messed up the formatting of the bash descriptions.
marckhouzam: @Luap99 Interesting find!  What do you think would be best for a user:
1. only taking the first line of the description or
1. escaping the newline and showing the entire description (if we can)

I'm asking because I wondered if truncating a description would remove useful information.
Do you have concrete examples of descriptions using a newline so we can judge what would be best?
Luap99: @marckhouzam Here are two examples I found in the podman project:
[tmpdir flag](https://github.com/containers/podman/blob/3d3359086ef0ed0833a8ac8e9d06d9934d835139/cmd/podman/root.go#L268)
[latest flag](https://github.com/containers/podman/blob/3d3359086ef0ed0833a8ac8e9d06d9934d835139/cmd/podman/validate/latest.go#L11)

I would argue that the first line should contain enough information to understand what a command/flag does. If someone wants the full information they should use the man pages or --help.

marckhouzam: LGTM 
This will protect both fish and zsh completions from descriptions that have a line break in them.

 Cobra can generate a shell-completion file for the following shells: Bash, Zsh, Fish, Powershell. If you add more information to your commands, these completions can be amazingly powerful and flexible.  Read more about it in [Shell Completions](shell_completions.md).
