info --shell output doesnt match docs

[tescalada]

heroku info myapp --shell doesnt produce the same results as the help documentation.

The help docs are correct and would be usable in a bash shell. The actual results are not easily usable for some fields.

Any fields that should have an _ are being replaced by a - because of the S(k).slugify().

const S = require('string')
S('git_url').slugify()
{ [String: 'git-url'] s: 'git-url', orig: 'git-url', length: [Getter] }

Example below (with personal info removed).

$ heroku help info myapp --shell
Usage: heroku info

show detailed app information

-a, --app APP # app to run command against
-j, --json
-r, --remote REMOTE # git remote of app to run command against
-s, --shell # output more shell friendly key/value pairs

Examples:

$ heroku apps:info
=== example
Git URL: https://git.heroku.com/example.git
Repo Size: 5M
...

$ heroku apps:info --shell
git_url=https://git.heroku.com/example.git
repo_size=5000000
...

$ heroku info myapp --shell
create-status=undefined
