Subject: [PATCH] Change the regexen in doBlockLevels() to handle <center> tags
 the same as <div>.  This fixes bug 8293: Use of center tag ruins paragraph
 formatting, but COULD SOMEONE PLEASE EXPLAIN TO ME WHY??!?  Trying to make
 sense of that code gives me a headache.  (Ps. See also related change in
 r14690.)
