Have you even tried?

For me it does not interrupt printing long result unless I put
something like this in shell.rb:

    def puts_iter str
        while str.length > 100
           STDOUT << str[0...100]
           str = str [100..-1]
        end
        STDOUT.puts str
    end

    # Prints result using #format_result
    def print_result(result)
      puts_iter(format_result(result)) unless @error_raised
    end

Either.

It does not like to complete absolute paths:

>> Bond.spy 'File.open "/'
Matches completion with condition /[\s(]["']([^'"]*)$/.
Possible completions: []
Matches for /[\s(]["']([^'"]*)$/ are [" \"/", "/"]
=> nil

Thanks
