samueljohn 0eb1cadee0 brew --config: properly handle empty which strings ...

Symptom: If no python/ruby/perl is in your path, then `which x`.chomp
returns an empty string and `unless ""` is still true.  So, N/A is never
displayed.  Instead, ruby's Pathname.new("").realpath returns the cwd.
(I consider this realpath behavior a ruby bug) Fix: use empty?

Closes Homebrew/homebrew#10027.
