[PATCH 1/1] Use correct /dev/null for UNIX and Windows




From: chris <chris@xxxxxxxxxxxx>

Use File::Spec->devnull() for output redirection to avoid messages
when Windows version of Perl is first in path.  The message 'The
system cannot find the path specified.' is displayed each time git is
run to get colors.
