 If a permalink accesses "/?feed=rss&foo=bar" in the state of being
 invalid, it will redirect to "/?feed=rss2 foo=bar" and "404 Not Found"
 will be displayed.

 procedure for reproducing:
 * If a permalink is effective, repeal.
 * Delete cash of a browser.
 *   "http://DOMAIN/?feed=rss&withcomments=1" is accessed.
 Result:
 *   "404 Not Found" is displayed.

 The cause was carrying out the miswritten word of the backreference by
 preg_replace.
 patch is miswritten word correction simply.
