BUG: ruby-mode.el /Today's Comic/

Hi all
This regexp seems to break ruby-mode parser or something like that (I'm
not an advanced emacs user)
This is the code:

  def image_data
    src = open("http://www.dilbert.com/").read
    soup = BeautifulSoup.new(src)
    url = soup.find('img', { :attrs => { 'alt' => /Today's Comic/ } })
    open("http://www.dilbert.com" + url['src'], "rb").read
  end

I'd appreciate if someone else tried this too. I'm using last version
of ruby-mode.el and Gnu Emacs 22.0.92.1

Cheers

It buggers up Vim's syntax highlighting as well, not sure how best to fix
it, but there is a work-around, the %r{} construct:

def image_data
   src = open("http://www.dilbert.com/").read
   soup = BeautifulSoup.new(src)
   url = soup.find('img', { :attrs => { 'alt' => %r{Today's Comic} } })
   open("http://www.dilbert.com" + url['src'], "rb").read
end

What's the actual problem? I don't see anything wrong - at least
<Tab> still sets the indentation correctly.

An obvious guess is that the "'" character is the problem. Try
escaping it: " /Today\'s Comic/ ". Of course I can't test this fix as
I don't see the problem!
