Vasil Dimov 15273e4310 (Builtin InnoDB) Fix Bug#59303 Correct URL in crash message
old URL: http://dev.mysql.com/doc/refman/5.1/en/forcing-recovery.html
new URL: http://dev.mysql.com/doc/refman/5.1/en/forcing-innodb-recovery.html

Notice that there is a redirect from the old URL to the new URL, so visiting
the old URL does not give "page not found" error.
