Brew prints this error:
```
Error: undefined method `join' for nil:NilClass
```
because, in this code:
```ruby
puts pinned_dependents.map do |f|
"#{f.full_specified_name} #{f.pkg_version}"
end.join(", ")
```
the block is passed to `puts` and not to `map`. `.join(",")` is called on the output of `puts`.
(I think the regression was introduced in this commit: e12a7b0808353ea81d63774be1edaff81710d7a6)
