Suppose I'm parsing the file and I see a </table> tag and I want to
find the matching <table> tag.  It could be pretty far back in the file.
That's what I was doing when I encountered this question.  But searching
backwards is a normal thing to want to do in general--for example it's
a standard command in any decent text editor.

Anyway, I just entered a sourceforge bug about it being missing from
Python's re module.
