My Perl must be getting rusty.  I had to look up this tricky syntax in
perlfunc.pod, under "=item exec", with examples like:

            $shell = '/bin/csh';
            exec $shell '-sh';		# pretend it's a login shell

        or, more directly,

            exec {'/bin/csh'} '-sh';	# pretend it's a login shell

If you mean by this that originally Jakub started and then Lea continued
extending the work, probably the order of Sign-off should match that order
to express the patch flow trail better.

Nice touch.
