+\r
+This might be something that the Git people could address if it was\r

+without going via a temporary file, which I doubt will fly.\r
+\r
+I suppose that I never actually considered merges on the IMAP server\r

+that means it needs to merge.\r

+\r
+I wonder if a custom merge driver could address this to properly use\r
+=E2=80=A6/tmp/ to assemble the message and only then move it.\r
