# Does a batch send using git-format-patch and git-send-email.  I like to
# have an intro message with all patches sent as replies to the intro msg.
# In a threaded mail reader, it would look like:
#
#      Intro message about patches
#          [PATCH] patch 1
#          [PATCH] patch 2
#          [PATCH] patch 3
#          ....
#
# By default, git-send-email sends each patch as a reply to the previous, so
# you get a nasty stairstep thing and no intro text.  It looks like this:
#
#      [PATCH] patch 1
#          [PATCH] patch 2
#              [PATCH] patch 3
#                  ....
