Seems deprecated for `each_line`. How about something like...

```ruby
config_re = /^config:add .* --remote=#{remote_name}/ # name TBD

File.open(RECORDER, 'r').each_line.grep(config_re) do |match|
  match.scan(/([A-Z_]+)=[^ ]*/) }.
end.flatten
```

I'm personally OK with `end.method` but I know some aren't.
