doc bug: match function: array argument: example output wrong

[David Chisholm]

$ gawk --version
-| GNU Awk 3.1.0

Document: Edition 3 of GAWK: Effective AWK Programming: A User's Guide for
GNU Awk, for the 3.1.0 version of the GNU implementation of AWK.

Section: 9.1.3 String Manipulation Functions

Discussing the match built-in function...

<BEGIN QUOTATION>
If array is present, it is cleared, and then the 0'th element of array is
set to the entire portion of string matched by regexp. If regexp contains
parentheses, the integer-indexed elements of array are set to contain the
portion of string matching the corresponding parenthesized sub-expression.
For example: 

  $ echo foooobazbarrrrr |
> gawk '{ match($0, /(fo+).+(ba*r)/, arr)
>           print arr[1], arr[2] }'
-| foooo barrrrr
<END QUOTATION>

When I ran the above code, the result was:
-| foooo bar 

Substituting '(bar*)' for the second parenthesized sub-expression yielded
the expected result.

Regards
