Wrong line numbers in errors

[Matthias Urlichs]

Version 5.2.15

see example script below, the unassigned $nope is reported to be in line 
4 which is obviously wrong. Removing the parentheses around the echo 
fixes the problem.

#!/bin/bash
set -u
( echo x ) | while read f ; do
    echo Test $f
    echo Test $f
    echo Test $f
    echo Test $f
    echo Test $f
done
echo $nope
