git-notify: Fix "global" notifications

If the number of commits included with a single push exceeds the maximum
specified via "-n", a single notification will be generated instead of
individual e-mails.  For listing the commits within such a notification,
git-rev-list(1)'s "--pretty" option is used.  This yields output which
the git_rev_list() subroutine didn't accept.  That's now fixed.
