Stephen, The --subject-prefix option applies to "git format-patch" when the local patch file is generated, as opposed to "git send-email". So my general workflow is to run "rm -rf /tmp/p ; git format-patch -o /tmp/p ..." and then examine the files in /tmp/p, and then if they look good, run "git send-email /tmp/p/*". I suspect it will be easier for Greg if you were to simply regenerate the patches with the proper subject prefix, and then resend them, since he has automation tools that can handle parsing the subject line, which scripts can do much more easily than to disentangling the "In-Reply-To" header to identify e-mail chains, and then parsing human/natural language to figure out which git tree the patches should be applied to. :-) Cheers, - Ted
