I added an additional optional boolean parameter called `fixListSpacing` to the `htmlEquals` utility function that can be set to `true` to run these regular expressions on the parsed and normalized editor XHTML in IE7-8 to removed the leading space before any `br`, `ul`, or `ol` elements in lists that is often added by those older versions of IE. This leading space was causing a lot of my tests for this ticket to fail, but using this new parameter to remove those leading spaces allowed all of my tests added in this ticket to pass in IE7-8. I figured this would be a generally useful parameter to have until we figure out some solution to get older versions of IE to stop adding that leading space before those elements.
