This:

https://en.wikipedia.org/wiki/Imperative_mood

but basically the sentence is a command.

So what I do after the whole set is applied, is:

git diff HEAD~<NUM>.. | ./scripts/get_maintainer.pl

where <NUM> is the number of patches which belong to the series.

IOW, you get a full diff of the set and you run that diff through
get_maintainer.pl.

It'll give you a whole lot of people but you can go through that list
and prune it to the people who are really relevant for the set.

And then you do

git send-email --cc-cmd=cccmd.sh ...

and that script simply echoes a "Cc: <name>" one per line. That is, if
there are a lot of people to Cc. If there are only 1-3ish or so, you can
supply each with the "--cc" option to git-send-email.

Anyway, this is what I do. Someone has probably a lot better flow tho.

Yeah, not even going there. :-)

HTH.
