link_to helper, popup option and IE window.open

Ah, the amount of time spent on this could have really been well spent elsewhere!

If you trying to use link_to as below:

  link_to "View Image", { :action => "view" }, :popup => ['new_window_name', 'height=300,width=600']
  # => View Image

Be very careful when you specify 'new_window_name'.

It shouldn't have any embedded spaces in the string.

Else IE will barf and throw a runtime exception! Firefox works fine though.
