Markdown-like emphasizing for text fields

Say you want to allow users to emphasize some string, but the whole markdown thing would be far too much. The helper method below does a basic replacement of **some text** with <strong>some text</strong>.

Usage: <%=md @question.title %>.

  def custom_markdown(prose)
    markdown = String.new.html_safe
    markdown << prose.to_str # make sure the prose gets escaped, even if it is an html_safe string
    markdown.gsub(/(\*\*)(.*?)(\*\*)/, '<strong>\2</strong>').html_safe
  end
  alias_method :md, :custom_markdown
