[1/1] scripts: Add add-maintainer.py
Commit Message
This script runs get_maintainer.py on a given patch file and adds its
output to the patch file in place with the appropriate email headers
"To: " or "Cc: " as the case may be. These new headers are added after
the "From: " line in the patch.
Currently, maintainers are added as "To: ", mailing lists are added as
"Cc: " and all others are addded as "Cc: " as well.
The script is quiet by default (only prints errors) and its verbosity
can be adjusted via an optional parameter.

Thanks Guru for submitting this script. In my limited testing, I don't
find any issues. It works as expected.
If I run this script on a series which spans across different lists,
there is a possiblity that we send partial series to certain lists. What
is the best way to deal with this? one way is to include union of all
lists in CC while sending the series with primary maintainer in TO. Can
the script print those values for easier workflow?
Thanks,
Pavan

Great! Thank you so much for testing this script.

Thanks for bringing this up - I was hoping to start a conversation on this.
Your suggestion seems logical to me. I can update v2 of this script adding an
`-a` flag that will add all maintainers to all patches following the scheme of
gathering the union of all maintainers, lists and "others" separately.
Hoping to get feedback from other maintainers on this point as well. Should I
expand the audience of this patch some more? I addressed this to whomever
`get_maintainer.pl -f ./scripts/` listed, plus Bjorn.
