Hi,

|i = 0

|could be better written as:

|string.split("\n").collect_with_index{ |i, s| '<p>' + i.to_s + " - " + s 
|}.join("\n")

I prefer this

  require 'stringio'

  s = StringIO.new
  string.each_with_index do |line, i|
    s.puts "<p>#{i} - #{line}"
  end

|However, is seeking completeness such a horrible thing?

No.  It's not bad.  It's not horrible.  It's just not a ultimate goal.
