Heh.  And you don't see that as a challenge?  Oh well, I could try :-)

Yes, but that isn't clear in your patch (series).

Not according to the changelog!

It is hard to find the five, six, ten places with modification in an
1800-line patch (or what was it).

Please make it less work for me to review your patches than it took you
to write them!  This often means you have to spend a bit more time and
thought on it.  As a side effect that makes better patches, you have
something to win here as well (apart from your patches being reviewed
easier :-) )
