Twenty Eleven sends argument to the_excerpt(), which doesn't take any
|Reported by:||coffee2code||Owned by:||nacin|
Unlike the_content(), the_excerpt() does not accept any arguments. The attempt to send a custom 'more' link text is futile and misleading.
This was also previously brought up in #13883 for Twenty Ten, so this appears to be a common misconception.
This was introduced in r17669 when Twenty Eleven was added to core.
Attached patch simply removes sending of the argument.
