This relates to my email a few minutes earlier about collect_with_index, but 
how would you do this without incrementing an index, given the current lack 
of existance of a collect_with_index method?

To take a string, split it into paragraphs, turn each of them into an HTML <p> 
and number them:

i = 0; string.split("\n").collect{ |para| '<p>' + (i += 1).to_s + " - " + para 
}.join("\n")
