This time (only), I'll try to fix them up at my end, but please check your toolchain, find out where the extra blank line between S-o-b: lines we see above come from, and fix that, so that I won't have to do so again.

It does not give any useful information to people who are reading the end result of applying this patch and is useful only in the context of comparing the old and new templates, iow, it belongs to the commit log message.

We'd need to clean up these no-op '' from this, but not doing so in this patch is perfectly fine (and is even preferred).

Thanks.
