I use Text::Format for this:

def wrap(text)
   formatter = Text::Format.new
   formatter.columns = 72 # 70 + '> ' = 72
   formatter.format_style = Text::Format::LEFT_ALIGN
   formatter.first_indent = 0

   formatted = []

   text.split(/\r?\n\r?\n/).each do |chunk|
     formatted << formatter.paragraphs(chunk)
   end

   return formatted.join("\n")
end
