Title: wrap unset of GIT_PAGER_IN_USE a lexical warnings disabler

Under 5.8 perls, doing

$ENV{GIT_PAGER_IN_USE} = undef

produces this warning:

Use of uninitialized value in scalar assignment at /home/jfitzgib/perlbrew/pkg/lib/5.8.8-linux-x86_64-linux-thread-multi/lib/perl5/Git/Wrapper.pm line 16.
