message_for(corrections)

Returns a human readable string that contains corrections. This formatter is designed to be less verbose to not take too much screen space while being helpful enough to the user.

@example

formatter = DidYouMean::Formatter.new

# displays suggestions in two lines with the leading empty line
puts formatter.message_for(["methods", "method"])

Did you mean?  methods
                method
# => nil

# displays an empty line
puts formatter.message_for([])

# => nil
