./configure is a generated script. Including it in the repository is not
something many projects do, since one of the things developers will be
working on is to change how that file is generated. Including it in the
release tar-balls is something every project (that uses autoconf) does,
since those are aimed at end-users.

It has not been the standard since before GNU, as the GNU project was
started quite a long time (well over a decade) before autoconf's inception.

I guess you're referring to the "To: " and "Cc: " fields of the emails
you received containing your address. For this particular list, that's
part of how we do things. It's quite common on high-volume lists to do
that, as people would otherwise have to sift through *all* the mail on
the list to figure out which emails are replies to their own questions
or patches. Somewhere in the Cc list you will see git@vger.kernel.org,
I'm sure.

Thank you for that.

And again, thank you for that.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
