For consistency this also means that it should be an error to use \3 if no
third subexpression exists. So I would suggest changing

The closing right parenthesis of this subexpression must occur before the
back-reference. 

to

"The regular expression is invalid if this subexpression does not exist or if
its closing right parenthesis occurs after the back-reference."
