Sorry, there was a bug in my script, found while running it on the
linux kernel (where the Signed-off-by stuff came from) to see if it
was different.  The corrected numbers are:

Author Signed-off-by comes after all non-Signed-off-by trailers: 2990
non-Signed-off-by trailers follow the Author's Signed-off-by line: 3069

So, this suggests it's even less of a rule.  For those curious, the
Linux kernel has these numbers:

Author Signed-off-by comes after all non-Signed-off-by trailers: 83530
non-Signed-off-by trailers follow the Author's Signed-off-by line: 199778
