Ok, so I remembered it the wrong way around, but it is a tool bug:

$ guilt patchbomb -s d480578..cd83c77
cd83c773 xfs: inode counter needs to use __percpu_counter_compare
1e41b5ad percpu_counter: batch size aware __percpu_counter_compare()
Are these what you want to send? [Y/n]

Note the use of "-s". from the man page:

           Don't add additional repository committer sign-offs to
           the patch.  This allows the sign-off chain to be fully
           expressed in the commit messages and not changed by the
           act of sending a patchbomb.

It would appear that the "-s" option is not working properly. I'll
fix that before sending the next round of patches....
