[bug #17454] Man page should describe parentheses

[Paolo Bonzini]

Update of bug #17454 (project grep):

                  Status:                    None => Fixed                  
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

   Precedence
       Repetition takes precedence over concatenation,  which  in  turn 
takes
       precedence  over  alternation.   A  whole expression may be enclosed
in
       parentheses  to  override   these   precedence   rules   and   form  
a
       subexpression.

   Back References and Subexpressions
       The back-reference n, where n is a single digit, matches the
substring
       previously matched  by  the  nth  parenthesized  subexpression  of 
the
       regular expression.
