Doh'oh. You're right of course. I just tested it on the command-line and by executing the scripts (Perl interprets the shebang itself):

    $ /usr/bin/env perl -w -le 'print $^W'

However. Isn't Perl 5.6 the lowest version Git aspires to be compatible with anyway? If that's the case they can just be changed to 'use warnings' across the board.
