[PATCH] change Perl syntax to support Perl 5.6

[Robert Schiele <rschiele@gmail.com>]

git-add--interactive has one Perl command that was not yet present in
Perl 5.6.  Changing this single command makes it compatible again.

This is an alternative to my previous patch that just declared Perl 5.8 to
be the required version.
