I would be happy if I can configure my "git show" to
- show not just patch but stat by default;
- keep showing nothing when told to be silent with "git show -s"
independently what happens to my "git log". Specifically, I do not
want to see a configuration that I use to tweak "git show" the way I
want (see above) to make my "git log" to become "git log --stat".
And why is "stat" so special? I am sure there are people who want
to do --numstat or --summary or combinations of these by default,
so I doubt that a new bit in rev_info structure is a good way to go.

Absolutely.

Nobody will get such a guarantee. A good test to see if a topic is
worth spending the reviewers' time on is if the authors are willing
to spend their time whether it will be in the official relesae or it
will have to be kept in a private fork for the authors' own use. If
it is not good enough that the authors won't keep a fork of Git just
to use it for themselves, it is hard to imagine that it would be
good enough for public consumption.
In short, make it so useful that we'd come to you begging for it ;-)

The change to the code we saw in builtin/log.c, e.g.

hints us that this new bit belongs to the group that the
combine_merges bit belongs to, not here, no?
But again, I am not sure if a new bit in rev_info structure is a
good way to proceed---after all, when a diff (in various forms, like
"patch", "stat only", "patch and stat", "patch, stat, and summary")
is shown, how exactly they are shown is not controlled by bits in this
structure (rather, that comes from the diffopt field).
Thanks.
